Correlation of Co[110]/Cr[002] texture and magnetic properties in CoCrTaPt granular films

Studies of the effects of substrate temperature T/sub s/ on the evolution of Co[110]/Cr[002] texture, magnetic and physical grain size, intergrain-interaction, anisotropy, orientation ratio of remanence and coercivity were investigated experimentally. It is found that the hcp-Co[110]/bcc-Cr[002] texture is improved with increasing T/sub s/ from 27/spl deg/C to 265/spl deg/C. The intergrain-interaction, magnetic and physical grain size decrease with increasing T/sub s/ and reach their minima at T/sub s//spl ap/265/spl deg/C where the magnetic grain size is close to the physical grain size. The correlation between the film microstructure and magnetic properties is studied systematically.
