XAFS MEASUREMENTS ON CO-K AND PT-L-III EDGES IN (111)COPT3 FILMS

XAFS measurements at the Co-K edge and Pt-L-III edge were performed in an (111) epitaxial CoPt3 film with strong perpendicular magnetic anis otropy. The analysis of XAFS data obtained using in-plane and out-of-p lane polarization show the existence of an anisotropic local order cha racterized by preferential heteroatomic pairs out of the him plane bal anced with preferential homoatomic pairs in the (111) plane. The isotr opic local order found in a magnetically isotropic CoPt3 film from Pt- L-III edge data should be confirmed by XAFS measurements on Co-edge.
