Studies of High Coercivity Cobalt-Phosphorous Electrodeposits

Abstract

Electrodeposited Co–P films have been prepared having coercivities of 1000 to 1300 oe in the plane of the film. The material has been studied by means of x-ray diffraction, electron microscopy, and the Craik technique. It is concluded that the material has a rod-like structure and that shape anisotropy is at least partially responsible for the observed coercivity. The magnetic properties of this material are compared with those of previously reported platelet materials. An attempt is made to explain the properties of both rod and platelet materials on the basis of single domain particle theory.

Magnetic Electrodeposits of Cobalt-Phosphorus

“…The 1300-oe material has the 002 plane strongly orientated in the plane of the deposit. The nature of the latter material is described elsewhere (6).…”
