- 論文の詳細を見る
The magnetic properties of GdCo_2 and Gd_<1-x>Y_xCo_2 have been observed and discussed in terms of the molecular field approximation. An appropriate set of interaction parameters reproduces the temperature dependence of the magnetization of GdCo_2 and the concentration dependence of the Curie temperature of Gd_<1-x>Y_xCo_2 for x<0.2. Among the three kinds of interaction, the interaction between Gd and Co atoms plays the most important role in determining the Curie temperature. A negative deviation of the Curie temperature form the molecular field estimation, observed for x>0.2, suggests that the Co moment is suppressed by Y substitution and quite sensitive to magnetic environments. A stepwise anomaly in the temperature dependence of the magnetization previously reported could not be observed.
