Magnetic anisotropy of monatomic Co layers on Pd(0Â 0Â 1) studied by soft X-ray magnetic circular dichroism

▶ In situ study of ultrathin films by X-ray magnetic circular dichroism (XMCD). ▶ The XMCD revealed magnetic properties of single monolayer Co films on Pd(0 0 1). ▶ The sandwich film of Pd/Co/Pd(0 0 1) shows perpendicular magnetic anisotropy (PMA). ▶ Orbital magnetic moment along the PMA axis is large at the Co site of Pd/Co/Pd(0 0 1). ▶ The XMCD hysteresis curve shows full magnetic remanence of the PMA film at 300 K.
