XAFS Measurements on Co-K and Pt-LIII Edges in (111) CoPt3 Films

C. Meneghini , M. Maret , M. Cadeville , J. Hazemann

XAFS measurements at the Co-K edge and Pt-LIII edge were performed in an (111) epitaxial CoPt3 film with strong perpendicular magnetic anisotropy. The analysis of XAFS data obtained using in-plane and out-of-plane polarization show the existence of an anisotropic local order characterized by preferential heteroatomic pairs out of the film plane balanced with preferential homoatomic pairs in the (111) plane. The isotropic local order found in a magnetically isotropic CoPt3 film from Pt-LIII edge data should be confirmed by XAFS measurements on Co-edge.
