Abstract

XAFS analysis of the local structure about Pt and Co in PtxCo1-x, for x to approximately 0.7 revealed that the local coordination of Co and Pt is similar to that found in cubic L12Pt3Co. In the plane of the films, significant Co-Co bonding was found, a feature not present in ordered L12Pt3Co. The presence of Co-Co bonds, preferentially in-plane, suggest that clustering of Co into `sheets' or `chains' is the source of PMA in these films.
