Sulfur Modified Chromium Dioxide

概要
- 論文の詳細を見る
It was found that sulfur ions dissolved in chromium dioxide up to about 3 atomic percent lowering both the Curie temperature, T_c, and the saturation magnetization, σ_s. As the amount of sulfur increased, the lattice constant of the crystal, a_o, increased from 4.423 Å to about 4.435Å, while no change was observed for c_o. The addition of sulfur did not change substantially the size of the powder. The coercive force, H_c, at room temperature was as much as 120 O_C. The combined addition of sulfur and tellurium, however, resulted in a fine acicular powder with a coercive force higher than 400 Oersted and a Curie temperature of about 100℃. This powder has potential use in thermal duplication of magnetic tape signals.
