Induced Magnetic Moments of 4d and 5d Elements in Thin Films and Multilayers by X-Ray Magnetic Circular Dichroism

摘要

Measurements of induced magnetic moments in magnetic thin films and multilayers are necessary for a better understanding of the magnetic properties, especially where spin-orbit coupling plays a crucial role like, for example, magnetic anisotropy, magnetoresistance etc. Progress in third generation synchrotron radiation facilities during the last about 20 years has made possible the determination of induced spin and orbital magnetic moments of 4d and 5d transition metal elements via element-specific techniques. In this work, X-ray magnetic circular dichroism results on the magnetic moments of some 4d and 5d elements in thin films and multilayers are briefly reviewed. The role of interatomic distances and coordination in the coupling between orbital and spin magnetic moment is discussed.
