Abstract

The effects of pretreatment (i. e. , activation and acceleration) and substrate species on the magnetic properties of Co-P electrolessly plated thin films for high density storage medium were investigated with various PdCl//2/SnCl//2 catalysts and accelerators. The activity of surfaces to be plated controlled the magnetic properties of Co-P thin films, and the coercivity became lower with increase in the catalytic activity of surfaces. The magnetic properties of Co-P films were also affected by the substrate species and were controlled by grain size of substrate surfaces, but the larger surface roughness which was produced by emery papers did not affect the magnetic properties.
