Title: Magnetic circular dichroism in Co1-xPtx nanowire bundles at the CoL2,3 edges

Abstract

Co1-xPtx nanowire arrays embedded in anodic aluminum oxidetemplates were fabricated by an electrochemical route. X-ray magneticcircular dichroism XMCD measurements were conducted at the Co L2,3 edgeson samples with an array of nanowire bundles at the substrate surfaces.The ratios between the orbital and the spin moments R were estimated tobe about 0.19+-0.03 and 0.07+-0.03 for 20 nm Co and 14 nm Co91Pt9nanowires, respectively. A strong temperature dependence of the R valuewas observed. The x-ray absorption spectra also indicated the presence ofCoO, which did not contribute to the XMCD signals.
