稀土-铁-碳化合物磁性的理论分析

Theoretical Analysis of Magnetic Properties of Rare Earth-Iron-Carbon Compounds

利用两个次晶格的分子场理论分析了稀土-铁-碳化合物的磁性,计算了分子场系数nFF,nRF,nRR以及自旋交换系数AFF,ARF,ARR,并对所得结果进行了讨论。

On the basis of a two -sublattice model,the magnetic properties of the intermetallic compounds are analyzed using the molecular-field theory.The molecular-field coefficients nFF,nRFand nRR and the spin-exchange parameters AFF,ARF and ARR are calculated,the rerults are discussed
