Temperature Dependent Magnetization and Remanent Magnetization in Pseudo-Binary x (Fe2TiO4)-(1-x)(Fe3O4) (0.30 < x < 1.00) Titanomagnetites

Abstract

In this work we present preliminary results on magnetization and remanence of synthetic pseudo-binary x(Fe 2 TiO 4 )-(1-x)(Fe 3 O 4 )(0.30 <; x <; 1.00). Magnetic characterization was performed at temperature ranges from 100 K up to 400 K. The final objective is to characterize the magnetic response as a function of temperature in order to foresight the future magnetic measurements of the magnetometer included into Met-Net mission to Mars. Samples present ferromagnetic behavior with Néel temperatures above the minimum Martian temperature. An increased remanence for sample with x=0.65 has been measured possibly originated by pinning mechanism which might offer a partial explanation as to the crustal magnetism of Mars.
