Tailoring the magnetic properties of CoFePtP alloys with variations in iron content

Abstract

We investigated the effects of iron content variation in electrodeposited CoFePtP alloys on the magnetic properties and microstructure. At an iron content of 4.3 at.%, the CoFePtP films exhibited a typical hard magnetic property, while at 13.8 at.% a soft magnetic property was observed. The preferred orientations of the electrodeposited films changed from [0 0 2] to [1 0 0] growth direction with increasing iron content in accordance with magnetic property variations.
