摘要

Half-metallic fully compensated ferrimagnets have attracted attention because they can be used asa spin injector with no stray field. Mn-Co-V-Al Heusler alloy is one of the candidates. Recently, themagnetization compensation for Mn_2(Co-V)Al Heusler alloy was experimentally showen and theCurie temperature was estimated to be around 650 K which was higher than room temperature.The half-metallicity of Mn_2(Co-V)Al was demonstrated by first principles calculation . However,there are no reports to fabricate the Mn_2(Co-V)Al film and to investigate the spin polarizationexperimentally. In this study, we investigated the magnetic properties of the Mn_2(Co-V)Al films andthe tunnel magnetoresistance (TMR) effect for the magnetic tunnel junctions (MTJs) with itselectrode to gain insight into its half-metallicity.
