| 摘 要： | 利用两格点分子场理论计算了ＲＦｅ３（Ｒ：稀土元素）、Ｒ２Ｆｅ１４Ｂ和ＲＦｅ１０Ｖ２化合物的ＨＲ（Ｔ）／ＭＦｅ（Ｔ）在不同温度下的数值。计算表明，ＨＲ（Ｔ）／ＭＦｅ（Ｔ）的数值随温度的升高而单调减小（Ｓｍ除外）。并给出了ＨＲ（Ｔ）／ＭＦｅ（Ｔ）的温度曲线用最小二乘法拟合的结果。 |

| Abstract: | By tising two-sublattice molecular field theory, the temperature- dependence of HR (T)/MFe(T) for RFe3, R2Fe14B and RFe10V2 compounds are calculated.The results indicate that the value of HR (T)/MFe(T) for these compounds decreases monotonous with temperature increasing. The fitting results of HR (T)/MFe (T) changing with temperature are also presented. |
