The reduction in the ordering temperature using a CoPt multilayer with an Au layer inserted was discussed. After annealing at 400°C, the coercivity of the CoPt multilayer with 2 nm Au inserted was 5 kOe. The addition of Au was effective for reducing the ordering temperature. It was found that the phase formation of the L1 0 structure of the CoPt inserted Au layer films started at around 350-400°C. The results show that the phase formation of L1 0 structure of CoPt is a slow diffusion process.
