MAGNETIC-PROPERTIES OF COPTCR THIN-FILMS WITH (1120) CRYSTAL ORIENTATION

The microstructure and magnetic properties of CoPtCr thin films with [112BAR0] 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.
