Temperature Dependent Magnetization and Remanent Magnetization in Pseudo-Binary ${\rm x}({\rm Fe}_{2}{\rm TiO}_{4})\hbox{-}(1-{\rm x})({\rm Fe}_{3}{\rm O}_{4})(0.30<{\rm x}<1.00)$ Titanomagnetites

Abstract

In this work we present preliminary results on magnetization and remanence of synthetic pseudo-binary <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">${\rm x}({\rm Fe}_{2}{\rm TiO}_{4})\hbox{-}$</tex></formula> <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex Notation="TeX">$(1-{\rm x})({\rm Fe}_{3}{\rm O}_{4})(0.30&lt;{\rm x}&lt;1.00)$</tex> </formula> . 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 <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex Notation="TeX">${\rm x}=0.65$</tex></formula> has been measured possibly originated by pinning mechanism which might offer a partial explanation as to the crustal magnetism of Mars.
