Origin of Perpendicular Magnetic Anisotropy in Co${}_x$Fe${}_{3-x}$O${}_{4+\delta }$ Thin Films Studied by X-ray Magnetic Circular and Linear Dichroisms

Jun Okabayashi, Masaaki A. Tanaka, Masaya Morishita +2

We investigate the element-specific spin and orbital states and their roles on magnetic anisotropy in the Co-ferrite (Co${}_x$Fe${}_{3-x}$O${}_{4+\delta }$ (001)) thin films which exhibit perp…
