Abstract

We investigate the magnetic properties of Fe_100-xV_x/MgO-based structures with a V composition x up to 20 at. %. The introduction of V results in the reduction of spontaneous magnetization, the damping constant, and both interfacial and bulk perpendicular magnetic anisotropies. However, the insertion of thin Fe layers at the FeV/MgO interfaces results in an effective perpendicular magnetic anisotropy as large as that of Fe/MgO. The result shows potential for lowering the threshold current for magnetization switching in FeV/MgO-based magnetic tunnel junctions, while maintaining a thermal stability factor similar to that in Fe/MgO-based junctions.
