| 摘 要： | 利用两格点分子场论(MFT),比较了R_nFe_m(n/m=1/3,6/23)和R_nFe_mM_k(M:类金属或其他金属;n/m/k=2/14/1;1/10/2)(即RFe_3,R_6Fe_(23),RFe_(10)V_2,RFe_(10)Mo_2,RF_(10)V_2N_x)两类化合物分子间的磁耦合系数;给出了Fe—Fe、R—R和R—Fe相互作用对居里温度的不同贡献。

| Abstract: | By using a two-sublattice molecular field theory (MFT), the coupling coefficients of the RoFem(n/m=l/3,6/23) and RoFemMk(M=metalloids and other metals;n/m/k=2/14/1, l/10/2)(or RFe3, R6Fe23,R2Fe14B ,RFe10V2 , RFe10Mo2 and RFe10V5Nx) have been compared. The contributions to Curie temperature due to Fe-Fe, R-R and R-Fe interactions are presented. |
