Abstract
We have prepared nanometer-size, isolated CoPt particles. The particle
s 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 magne
tic coercivity as high as 30 kOe were achieved. The results indicate t
hat the high magnetic coercivity was obtained because the crystallite
size approaches that the noninteracting single-domain particles. (C) 1
