Abstract
This study investigates the interfacial magnetic anisotropy of M/Fe/MgO(001) stack structures (M = Au, Pt). Ab initio calculation studies show that the interface strain due to lattice mismatch could enhance the electric field effect on the magnetic anisotropy energy. The perpendicular magnetic anisotropy energy is calculated based on the free energy difference associated with spin orientation.
