Publicación Acceso Abierto Small Fluxgate Magnetometers: Development and Future Trends in Spain(Multidisciplinary Digital Publishing Institute (MDPI), 2010-03-09) Ciudad, D.; Díaz Michelena, Marina; Pérez, Lucas; Aroca, C.; Ministerio de Educación y Ciencias (MEC)In this paper, we give an overview of the research on fluxgate magnetometers carried out in Spain. In particular we focus in the development of the planar-type instruments. We summarize the fabrication processes and signal processing developments as well as their use in complex systems and space.Publicación Acceso Abierto Gamma Irradiation of Magnetoresistive Sensors for Planetary Exploration(Multidisciplinary Digital Publishing Institute (MDPI), 2012-04-02) Sanz, Ruy; Fernández, A. B.; Domínguez, J. A.; Martín Vodopivec, B.; Díaz Michelena, MarinaA limited number of Anisotropic Magnetoresistive (AMR) commercial-off-the-shelf (COTS) magnetic sensors of the HMC series by Honeywell, with and without integrated front-end electronics, were irradiated with gamma rays up to a total irradiation dose of 200 krad (Si), following the ESCC Basic Specification No. 22900. Due to the magnetic cleanliness required for these tests a special set-up was designed and successfully employed. Several parameters of the sensors were monitored during testing and the results are reported in this paper. The authors conclude that AMR sensors without front-end electronics seem to be robust against radiation doses of up to 200 krad (Si) with a dose rate of 5 krad (Si)/hour and up to a resolution of tens of nT, but sensors with an integrated front-end seem to be more vulnerable to radiation.Publicación Restringido Design of a Portable Susceptometer With No Electromagnets(Institute of Electrical and Electronics Engineers (IEEE), 2023-12-04) Rivelles García, Alejandro; Sanz Lluch, María del Mar; Maicas, Marco; Mesa, José Luis; Díaz Michelena, Marina; Aroca, Claudio; Ministerio de Ciencia e Innovación (MICINN); European Research Council (ERC)Magnetic materials characterization usually requires heavy equipment based on electromagnets, which limits their use to the laboratory. The volume of the typical samples is small in order to keep a good uniformity of the applied magnetic field in the sample. This kind of equipment is not appropriate for geological measurements in the field, where portable systems are required and samples have typically a higher volume. Here, we study the limits and applicability of a portable susceptometer device based on strong magnets potentially applicable in geological prospections. A new prototype has been built and tested. The device makes use of Nd–Fe–B magnets and an iron magnetic circuit (MC) to apply the magnetic field to the sample. A quasi-spherical geometry of the MC provides good uniformity of the magnetic field while keeping a moderate measuring volume. The equipment is powered by a 12-V battery and a mechanical design allows the control of the magnetic flux density in the range of approximately 30–130 mT.Publicación Restringido Design of a planetary protection cover for EMC testing of a spacial magnetic sensor(Institute of Electrical and Electronics Engineers, 2019-10-17) Fernández Romero, S.; Parrondo, María Concepción; Díaz Michelena, Marina; Muñóz Rebate, I.; León Calero, Marina; Martín Iglesias, Santiago; Plaza Gallardo, Borja; Escot Bocanegra, D.; Poyatos Martinez, David; Jiménez Lorenzo, María; López Sanz, Daniel; Ministerio de Economía y Competitividad (MINECO); Agencia Estatal de Investigación (AEI)This paper explains the research process carried out for the development and manufacture of the planetary protection cover for carrying out the electromagnetic compatibility (EMC) tests of the an-isotropic magneto-resistance (AMR) sensor of the ExoMars 2020 mission. This mission has strict bioburden requirements. The electromagnetic properties of several materials have been analyzed in order to study their transmission coefficient and the innovation of this project is the use of fused deposition modeling (FDM) technology as manufacturing method. Additive manufacturing is presented as a promising technology in the field of radiofrequency since it can use a wide range of polymeric materials (thermoplastics) with low transmission coefficient. Observing the electromagnetic (EM) characterization results, it was decided to manufacture a protective cover using FDM technology, because it allows control over the grounding of the instrument and facilitates the integration, cleaning and protection against impacts during the manipulation, with great versatility and low cost. Finally, the cover has been verified during the acceptance EMC tests of the flight model AMR instrument.Publicación Acceso Abierto Vector magnetometry to analyse the Caldereta volcano in the canary islands as a possible terrestrial analogue of mars(Elsevier, 2025-04-07) Díaz Michelena, Marina; Losantos, Emma; Rivero Rodríguez, Miguel Ángel; Oliveira, Joana S.; García Monasterio, Óscar; Mansilla, Federico; Melguizo, Ángel; García Bueno, Jose Luis; Salamanca, David; Fernández Romero, S.; Ministerio de Ciencia e Innovación (MICINN); European Research Council (ERC)Volcanoes are typical features of terrestrial planets' surfaces. Among the different geological processes which give rise to volcanoes, hydromagmatic eruptions are of particular importance for the search of extraterrestrial life since they require the presence of water. Phreatomagmatic eruptions on Mars shall resemble those of the Earth. The possibility to perform magnetic surveys on Mars with magnetometers carried by helicopters opens a new scenario to gain more insights on such features. As a natural first step, gathering a database of terrestrial analogue magnetic signatures is desired, prior to magnetic surveys on the Martian surface. In this work we have selected the Caldereta volcano, a phreatomagmatic edifice in Lanzarote Island (Canary Islands), to perform a magnetic survey using on board drones magnetometry. The acquired data will allow to compare future measurements from other similar structures of the “Red Planet”. The survey casts vector magnetic field data generated by the volcanic edifice. Additionally, we suggest a simplified structure that mimics the geomorphology observed, we attribute a magnetization to such structure and develop a mathematical model that computes its sourced magnetic field. Finally, we develop synthetic models of a volcano on Mars which have been preliminarily classified as hydromagmatic taking Caldereta simulated structure as a reference.Publicación Restringido Magnetic giant magnetoresistance commercial off the shelf for space applications(AIP Publishing, 2008-02-13) Díaz Michelena, Marina; Oelschlägel, W.; Arruego, Ignacio; Del Real, R. P.; Mateos, J. A. D.; Merayo, J. M.The increase of complexity and miniaturizing level of Aerospace platforms make use of commercial off the shelf (COTS) components constitute a plausible alternative to the use of military or rad-tolerant components. In this work, giant magnetoresistance commercial sensors are studied to be used as COTS, the next missions to be launched in the framework of the Spanish National Space Program: OPTOS and SEOSAT. This technology of magnetic sensors is interesting due to their high operating range up to 2mT and the high temperature dynamic range from −50 up to 150°C. However, in contrast, it presents high hysteresis and nonlinearity, temperature dependence, and poor repeatability. To improve the hysteretic, nonlinear and nonrepetitive behavior, a method consisting of a combination of reset and biasing has been designed and implemented for the ±75𝜇T linear region centered around 300–375𝜇T biasing field.Publicación Restringido A Sol–Gel based magneto-optical device for the NANOSAT space mission(Springer Link, 2009-03-31) Zayat, M.; Pardo, R.; Rosa, G.; Del Real, R. P.; Díaz Michelena, Marina; Arruego, Ignacio; Guerrero, H.; Levy, D.On December 2004, the Spanish Space Agency INTA (Instituto Nacional de Técnica Aeroespacial) launched the first nanosatellite called NANOSAT (Fig. 1) on board an European rocket Ariane 5, from the French Guyana. The satellite consists of a hexagonal device of <19 kg of weight with a diameter of about 50 cm, which describes a LEO orbit of 655 km of altitude. The main objective of the satellite is to probe the operation and performance of micro- and nanotechnologies in space environment. One of the scientific experiments implemented on board was the Sol–Gel based magnetic nanosensor.Publicación Acceso Abierto Magnetometric Surveys for the Non-Invasive Surface and Subsurface Interpretation of Volcanic Structures in Planetary Exploration, a Case Study of Several Volcanoes in the Iberian Peninsula(Multidisciplinary Digital Publishing Institute (MDPI), 2022-04-24) Díaz Michelena, Marina; Kilian, R.; Ángel Rivero, M.; Fernández Romero, Sergio; Ríos, F.; Mesa, José Luis; Oyarzún, A.; Instituto Nacional de Técnica Aeroespacial (INTA); Agencia Estatal de Investigación (AEI); European Commission (EC)Volcanoes are typical features of the solar system that offer a window into the interior of planets. Thus, their study can improve the understanding of the interiors and evolution of planets. On Earth, volcanoes are monitored by multiple sensors during their dormant and active phases. Presently, this is not feasible for other planets’ volcanoes. However, robotic vehicles and the recent technological demonstration of Ingenuity on Mars open up the possibility of using the powerful and non-destructive geophysical tool of magnetic surveys at different heights, for the investigation of surfaces and subsurfaces. We propose a methodology with a view to extract information from planetary volcanoes in the short and medium term, which comprises an analysis of the morphology using images, magnetic field surveys at different heights, in situ measurements of magnetic susceptibility, and simplified models for the interpretation of geological structures. This methodology is applied successfully to the study of different examples of the main volcanic zones of the Iberian Peninsula, representative of the Martian intraplate volcanism and similar to Venus domes, as a preparatory action prior to the exploration of the rocky planets’ surfaces.Publicación Acceso Abierto Vector Magnetometry Using Remotely Piloted Aircraft Systems: An Example of Application for Planetary Exploration(Multidisciplinary Digital Publishing Institute (MDPI), 2021-01-23) Fernández Romero, S.; Morata Barrado, P.; Rivero Rodríguez, Miguel Ángel; Vázquez Yañez, G. A.; De Diego Custodio, E.; Díaz Michelena, Marina; Agencia Estatal de Investigación (AEI); Fernández Romero, S. [0000-0002-7169-2222]; Vázquez Yañez, G. A. [0000-0002-8765-3068]Geomagnetic prospection is an efficient and environmentally friendly geophysical method for the analysis of the magnetic minerals’ distribution in the subsurface. High-resolution measurements require on-ground campaigns. However, these activities might imply high costs, risk and time consumption. Some more recent works have started to use magnetometers on-board remote piloted aircrafts. Normally, they fly at a constant altitude and use scalar probes. This configuration permits the determination of the magnitude of the magnetic field but not the direction, and requires advanced techniques for in-depth interpretation of the sources. In this manuscript, we describe the accommodation of a system for vector magnetometry in a drone whose flight altitude follows the elevation of the terrain. This singularity improves the capability of interpretation, including constraints in dating due to the record of the geomagnetic field. The work consists of the design, development and implementation of a solidary payload system anchored to the body of the platform in order to determine the vector magnetic field. It describes the details of the system and the performance characteristics obtained after the calibration, as well as its demonstration via a field campaign in the spatter deposits of Cerro Gordo volcano in Campos de Calatrava volcanic province in Spain.Publicación Acceso Abierto A novel induction-based device for the measurement of the complex magnetic susceptibility(Elsevier, 2017-08-13) Díaz Michelena, Marina; Mesa, José Luis; Pérez jiménez, M.; Maicas Ramos, M. C.; Cobos Arribas, P.; Hernández Ros, C. A.; Mesa, José Luis; European Research Council (ERC)A device named magnetic susceptometer for a complete determination of the magnetic complex susceptibility of materials and minerals has been conceived and manufactured as a complement for the in situ characterization of rocks during high resolution magnetic prospections. In this work a device and its capabilities for susceptibility measurements are described, the calibration performed with artificial samples, and the values of real and imaginary susceptibility of natural samples in a range comprising: χ = 10−4 to 10−7 [SI], representative of Earth and also Mars rocks.
