The dependency of coercive force Hc value on reciprocal thermal diffusion of Cr and Co for ion-beam-deposited films

We arrived at a conclusion that the key factor for coercive force Hc increasing was preferring orientation (PO) HCP CoNi(110)/Cr(200) deposition after we had examined the dependence of Hc value on structure. We also determined there that some small amount of disoriented HCP CoNi phase was nessicity to obtain maximum Hc value. The investigation of such films profiles by SIMS analyze method to determine the thermal diffusion mechanism in the films on substrate temperature was the aim of present work.
