Abstract
Novel thin film materials comprised of certain Co-based alloys containing phosphorous, i.e., Co-Cr-P-Pt or Co-Cr-P-Ni alloy, which can provide a high coercive force and a high squareness ratio are disclosed. These magnetic thin film alloys exhibit excellent magnetic properties without heating the substrate or applying bias thereto during the film formation and when glass is used for the substrate as well as an Al alloy disk.
