Magnetic properties of CoPtCr thin films with 〈112̄0〉 crystal orientation

Abstract

The microstructure and magnetic properties of CoPtCr thin films with 〈112̄0〉 restricted fiber texture grown on (100) planes of Cr single-crystal films were characterized and subsequently correlated with the domain configuration during the magnetization reversal process. These films exhibited a bicrystal mode associated with two orthogonal easy axes of magnetization in the plane of the film. The domain configuration of these films during the magnetization-reversal process consisted of two sets of domains extending in two orthogonal directions. These properties were compared with those of CoPtCr films with random crystallographic orientation.
