Publicación Acceso Abierto The diverse meteorology of Jezero crater over the first 250 sols of Perseverance on Mars(Nature Publishing Group, 2023-01-09) Rodríguez Manfredi, J.

Here we present measurements from the instrument’s first 250 sols of operation, revealing a spatially and temporally variable meteorology at Jezero. We find that temperature measurements at four heights capture the response of the atmospheric surface layer to multiple phenomena. We observe the transition from a stable night-time thermal inversion to a daytime, highly turbulent convective regime, with large vertical thermal gradients. Measurement of multiple daily optical depths suggests aerosol concentrations are higher in the morning than in the afternoon. Measured wind patterns are driven mainly by local topography, with a small contribution from regional winds. Daily and seasonal variability of relative humidity shows a complex hydrologic cycle. These observations suggest that changes in some local surface properties, such as surface albedo and thermal inertia, play an influential role. On a larger scale, surface pressure measurements show typical signatures of gravity waves and baroclinic eddies in a part of the seasonal cycle previously characterized as low wave activity. These observations, both comPublicación Acceso Abierto Asymmetrical magnetization processes induced by compositional gradients in ferromagnetic nanowires(Elsevier, 2024-01-16) Fernández González, Claudia; Berja, Alba; Álvaro Gómez, Laura; Martín-Rubio, Carolina; Mascaraque, Arantzazu; Aballe, Lucía; Sanz, Ruy; Pérez, L.; Ruiz Gómez, Sandra; Centros de Excelencia Severo Ochoa, INSTITUTO MADRILEÑO DE ESTUDIOS AVANZADOS EN NANOCIENCIA, SEV-2016-0686Electrodeposited nanowires are an excellent scenario to study and control magnetic domain wall motion in nanostructures. In particular, the introduction of local changes in composition during the growth procedure has been proven to be very efficient for controlling the magnetization dynamics. In this work, we show the possibility of introducing compositional gradients in FeNi electrodeposited nanowires by gradually changing the Fe/Ni ratio along their axis. These compositional gradients produce an asymmetrical landscape for domain wall motion which is reflected in asymmetrical magnetization processes under an applied magnetic field. By studying nanowires with different compositional gradients we were able to correlate composition and magnetic asymmetry. Our results pave the way towards full control of the movement of domain walls along the nanowires.Publicación Restringido Magnetic Characterization of Permalloy Nanodome Surfaces on Flexible PEEK/TiO2 Vertical Nanotubes Composites(IEEE, 2022-10-10) Martín-Rubio, Carolina; Rivelles García, Alejandro; Schneider, Marc; del Hoyo Gordillo, Juan Carlos; Privitera, V.; Worgull, M.Poly-ether-ether-ketone (PEEK) composites present outstanding physical and chemical properties, including radiation tolerance and compatibility with vacuum and additive manufacturing processing. Applications of PEEK range from biomedical to aerospace. Controlled 3-D nanostructuring arises as a powerful approach to generate new phenomena suitable for technological applications. In this sense, we target to synthesize robust and shapeable magnetic nanocomposites (NCs) for sensing and electromagnetic shielding applications. For this aim, we synthesized and characterized Permalloy (Py, Ni80Fe20) nanostructured surfaces on PEEK/TiO2. These NCs were synthesized by scalable and high throughput compatible fabrication approaches: anodization (TiO2 nanotubes) and hot embossing (thermal nanoimprint). The resulting NCs are shapeable, stable below 300 °C, and vacuum compatible. Their surfaces compose TiO2 nanodomes filled by PEEK. Py layers (15 nm) were sputtered on NC and flat PEEK films. The characterization included SEM, AFM, ISO-2409 Adhesion Tests, hysteresis loops, and first-order reversal curves (FORCs). The results revealed that both types of films keep stable characteristics after bending cycles, and noticeable modifications of the magnetic global response and local interactions generated due to the 3-D nanostructure.Publicación Restringido Asymmetric magnetic response induced by compositional gradients in Ni-Fe nanowires(IEEE Nanotechnology Council (NTC), 2024-07-09) Fernández González, Claudia; Gómez Cruz, Lucía; Álvaro Gómez, Laura; Berja, Alba; Martín-Rubio, Carolina; Waqas Khaliq, M.; Foerster, Michael; Niño, M. Ángel; Mascaraque, Arantzazu; Sanz, Ruy; Aballe, Lucía; Pérez, Lucas; Ruiz Gómez, Sandra"The control over the domain wall motion in cylindrical nanostructures is a key factor for developing the next generation of spintronic and logic devices [1,2]. Among several strategies, introducing changes in the chemical structure of the wire (chemical barriers) has been proved to be an effective way to pin the domain walls [3], but determining the direction of the domain wall movement still remains as an open challenge. Following the same approach, in this work we introduced gradients of composition in Ni-Fe nanowires to pattern a ratchet profile of the domain wall energy along the nanowire axis, in order to create an asymmetry for the domain wall movement. Nanowires were synthesized using template assisted electrodeposition. Composition was gradually changed between Ni90Fe10 to Ni35Fe65 along the nanowire longitudinal axis in periods of a few micrometres (fig.1.a). Combining laterally resolved X-ray Absorption Spectro-microscopy (XAS) and X-ray Magnetic Circular Dichroism (XMCD) we correlate the chemical structure of single nanowires with their 3D spin texture. By applying external magnetic fields along the nanowire axis, we studied the evolution of the magnetic state depending on the field direction. In addition, First Order Reversal Curves (FORC) were also measured in arrays of nanowires. The FORC diagrams of nanowires with homogeneous composition and nanowires with axial gradients of composition are shown in fig.1.b-c. While the diagram of homogeneous nanowires is highly symmetric with respect to the interaction field axis (HU)(b), an asymmetry arises in the diagram of nanowires with axial gradients (red square) (c), evidencing the emerging of asymmetrical magnetization processes in the nanowires [4]."Publicación Restringido Nanostructured metamaterials for the thermal and electromagnetic isolation of cryostats(SPIE, 2024-08-26) Vivas, Laura G.; Ramos Somolinos, D.; Martín-Rubio, Carolina; Rivelles García, Alejandro; Madueño Custodio, Laura; Ruiz Clavijo, Alejandra; Díaz, Alberto; Schneider, Marc; Plaza Gallardo, Borja; Poyatos Martinez, David; Del Hoyo, J. C.; Caballero Calero, Olga; Worgull, M.; Martín Iglesias, Santiago; Martín Vodopivec, B.; Maicas, M.; Navas, David; Martín González, Marisol ; Sanz, RuyIn terms of thermal and electromagnetic isolation properties, Nanostructured Metamaterials may present important advantages compared to current employed materials. In this work, we present the synthesis routes and the preliminary characterization results of some metamaterials based on Poly-ether-ether-ketone and nanostructured anodic oxides, with low thermal conductivity, combined with Au nanocolumns and three-dimensional nanonetworks. The results reveals proper magnetic and electromagnetic properties and suggest their suitable use under vacuum and cryogenic conditions.Publicación Restringido Magnetic interactions in ordered cobalt three-dimensional nanonetworks(EMS, 2023-08-27) Ruiz Clavijo, Alejandra; Caballero Calero, Olga; Navas, David; Vivas, Laura G.; Martín-Rubio, Carolina; Sanz, Ruy; Martín González, Marisol ; Agencia Estatal de Investigación (AEI)"Three-Dimensional (3D) magnetic nanostructures allow the generation and control of new effects able to give rise to the next generation of functional magnetic nanostructured metamaterials and devices[1]. This work reports the results on the synthesis and characterization of different interconnected Co nanowires forming a dense and ordered magnetic system: Co 3D Nanowire Networks (3DNN). These nanostructures were synthesized by the electrodeposition of Co in 3D ordered porous alumina templates [2] [3] [4]. The route allows to control the order and some geometric features compared to other synthesis approaches [1]. The resulting 3DNN consists of hexagonal ordered nanowires with an inter-wire distance of 65 nm and 50 nm in diameter. These nanowires are interconnected with a net of perpendicular or transversal nanowires (TNW) of ≈ 30 nm in diameter. Meanwhile the TNW are distributed in levels with a well defined distance between them of 550 nm. The magnetic characterization consisted in hysteresis loops, first magnetization curves and first order reversal curves (FORC) at 0º (in-plane, IP) 30º, 60º and 90º (out of plane, OOP) from perpendicular NW main axis. 1.D.
