Co/Pd multilayers (MLs) are candidate spintronics materials possessing perpendicular magnetic anisotropy (PMA) which can be utilized for the high-density recording technology [1]. The 4d transition metal (TM) system of Pd is well recognized as the sustainable elements of 5d TM system when combined with the magnetic 3d TMs. In order to understand the mechanism of PMA in Co/Pd MLs, the contributions of orbital magnetic moments of each element have to be clarified explicitly. Our aim in this study is to discuss both orbital and spin moments of Co and Pd for PMA in different anisotropy samples by using angular-dependent X-ray magnetic circular dichroism (XMCD) in Co L-edge and Pd M-edges.
