The effect of the oxidation of the Co ferromagnetic layer on gate modulation of its coercivity was experimentally investigated in Pt / Co / Al-O heterostructures. The Co surfaces were naturally oxidized by exposing to atmosphere after Co layer growth, and the degree of oxidation was characterized by x-ray photoelectron spectroscopy (XPS). A comparison between XPS and magneto-transport results suggested that a moderate oxidation of the Co interface enhances the electric-field induced coercivity change, indicating the importance of interface engineering for electrical control of magnetization reversal.
