概要

論文の詳細を見る
Experimental results are reported of the magnetic properties of telluride of cobalt, CoTe_x, where x is the molal content of tellurium. Measure -ments of the magnetization have been made over a range of temperatures between liquid air and 1150℃. The results of these measurements show that this compound, when stoichiometric, possesses a ferromagnetic character. The value of the saturation magnetization is 7.52 gauss per gram (0.25_<μB>). Evidence was found of a magnetic transition with a sudden disappearance of ferromagnetism at about 1000℃. These characteristic magnetic properties are similar to those of MnAs studied by Guillaud. Increase in tellurium content decreases the saturation moment of this compound, and when x is equal to 1.20 the compound is no longer ferromagnetic but shows a feebie constant paramagnetism which is independent of temperature.
