摘要
本文用两格点分子场论（ＭＦＴ）分析了Ｒ２Ｆｅ１７－ｘＭｘ金属间化合物磁性质与温度的关系。得出了ＨＲ（Ｔ）、ＨＦＢ（Ｔ）和ＨＲ（Ｔ）／ＭＦＢ（Ｔ）与温度的关系曲线和分子场系数ｎＲＲ、ｎＲＦ和ｎＦＦ。
In this paper, the temperature dependence magnetic properties of intermetallic compounds R 2Fe 17-x M x have been analysed by using two sublatticed molecular field theory (MFT).The curves of H R(T)H Fe (T) and H R(T)/M Fe (T) changing with temperature and the MFT coefficient n RR 、 n RF and n FF are obtained. The results show that the MFT based on a two sublattice model is capable of accurately describing the temperature dependence of the magnetization for these compounds.
