Abstract
We have studied the effects of a seed layer of vanadium on the anisotropy of the full-Heusler alloy Co2FeSi (CFS) for application as a perpendicularly anisotropic ferromagnetic layer for a current-perpendicular-to-plane giant magnetoresistance device. Perpendicular magnetic anisotropy (PMA) was estimated from the susceptibility in the linear magnetizing region of hysteresis loops for various layer thicknesses of CFS. Introduction of a second vanadium interface with the CFS was found to increase the observed PMA to a value of $K = 3.4\times 10^{4}$ erg/cm3. Basic spin-valve structures were fabricated to investigate the effect of spacer layers on two layers of CFS.
