Eight CoCrX(X=Pt,Ta,Ni) films with the same configuration of CoCrX(50 nm)/ Cr(200 nm)/polyimide were selected to investigate the effect of the substrate temperature (Ts) on the structural and magnetic properties. Special attention is paid to the hysteresis loss measurements. In general, a higher Ts tends to increase the Ms, Kl and the hysteresis loss parameters, and to reduce the OR// and S* values. The addition of Pt, Ta or Ni elements into Co-Cr film favours an increase in Ms and He// as well as a reduction in S* in varying degrees. It was found that the change in magnetic properties with respect to Ts for CoCiTa and CoCrPt films is quite different from that for CoCr and CoCrNi films.
