摘要：

We have prepared nanometer-size, isolated CoPt particles. The particles in the range of 100-300 nm in diameter were formed by annealing thin films in the temperature range of 550-800 degrees C. Films with magnetic coercivity as high as 30 kOe were achieved. The results indicate that the high magnetic coercivity was obtained because the crystallite size approaches that the noninteracting single-domain particles. (C) 1996 American Institute of Physics.
