Abstract

We have investigated the electric field (EF) effect on the magnetic anisotropy energy (MAE) in the thin films MgOMFeAu(001) and MgOFeM(001) (M=Pd, Pt, and Au) by means of first-principles density-functional calculations. We find that the MAE varies linearly with the EF and investigate the change in slope of the MAE as a function of the EF as the buffer layer is changed. We find that a single monatomic buffer layer may be useful for devices that use EF-modified MAE. We simulate the critical EF for easy-axis rotation and discuss interface effects of MgFe and FeAu on MAE.
