Abstract

The magnetic properties and microstructure of electroless-plated CoNiReP films, which varied primarily in their cobalt content, were investigated in order to clarify the origin of their magnetic anisotropy. The films, which showed perpendicular magnetic anisotropy, contained approximately 25 to 40% cobalt. They also had a higher crystallinity and better c-axis orientation than does hcp cobalt. It is thought that the anisotropy of these films is due mainly to the crystalline anisotropy deriving from the microstructure, and that the smaller saturation magnetization values, which act to decrease the demagnetizing field, enhance the anisotropy. The shape anisotropy caused by segregation in films is also thought to affect the overall anisotropy.
