Abstract

X-ray spectroscopy measurements have been performed on a series of PtCoAl Ox trilayers to investigate the role of Co oxidation in the perpendicular magnetic anisotropy at the CoAl Ox interface. It is observed that varying the degree of oxidation modifies the magnetic properties of the Co layer, inducing a magnetic anisotropy crossover from in plane to out of plane. The microscopic structural properties are analyzed via x-ray photoelectron spectroscopy measurements. It is shown that increasing the oxidation time enhances the amount of interfacial oxide, which may be at the origin of perpendicular magnetic anisotropy.
