- 論文の詳細を見る
The effects of annealing on the in-plane coercivity and the crystal structure have been investigated for sputtered Co-Pt alloy thin films with Pt content between 0 and 50 at.%. The coercivity of a Co_<50>Pt_<50> film drastically increases at annealing temperatures above 800 K. The coercivity increase corresponds to the formation of an L1_0 ordered phase, which is formed by the annealing at 940 K in less than 1 h. A maximum coercivity of 920 kA/m (11.5 kOe) is more than that reported for a bulk Co-Pt alloy. The grain size drastically increases in the early stage of annealing. (The grain size should be decreased for the use of the Co-Pt films as high-density recording media.)
