Magnetization of Co(S_xSe_1−x)₂ under High Magnetic Field Up to 500 kOe

Abstract

Proceeding the previous paper (J. Phys. Soc. Jpn. 46 (1979) 1474) the high field magnetization process of Co(S_xSe_1−x)₂ system for 0.70≤x≤1.00 has been investigated by means of pulse fields up to 500 kOe at fixed temperatures. The metamagnetic behaviors were observed and the phase diagram between the transition field and temperature was given. The saturation moment seemed to disappear at x\simeq0.6.
