Abstract
We have studied the effects of a seed layer of vanadium on the anisotropy of the full-Heusler alloy Co2FeSi for an application as a perpendicularly anisotropic ferromagnetic layer for a current-perpendicular-to-plane giant magnetoresistance (CPP-GMR) device. Perpendicular magnetic anisotropy (PMA) was estimated from the susceptibility in the linear magnetising region of hysteresis loops for various layer thicknesses of Co2FeSi. Introduction of a second vanadium interface with the Co2FeSi was found to increase observed PMA to a value of K = 3.4x104 erg/cm3. Basic spin-valve (SV) structures were fabricated to investigate the effect of spacer layers on two layers of Co2FeSi.
