Abstract :
Studies of the effects of substrate temperature Ts 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 Ts from 27°C to 265°C. The intergrain-interaction, magnetic and physical grain size decrease with increasing Ts and reach their minima at Ts≈265°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
