Modified Magnetism at Buried ColPd Interface: Depth-Resolved Magnetic

Abstract

Soft x-ray standing waves produced by a multilayer interference substrate add depth-sensitivity to magnetic circular

dichroism to 없이ve changes in Co magnetism across a 10 Å distance fro~ the Co ceñter to the Co-Pd

interface of a PdJCo/Pd trilayer having in-plane magnetization. Large enhancements of in-plane orbital and

spin magnetic moments, as weU as the number of d holes, are strongly localized in a thin interface layer. These

results provide new insight into the phenomenon of magnetic anisotropy at buried interfaces, and suggest a

broad applicability of such standing wave measurements to interface magnetism studies.
