| Abstract: | The temperature dependence magnetic properties of the R 2Fe 17- x M x and R 2Fe 17 N 3(R=Ce,Pr,Nd; M =Al; x =0.2)compounds are analyzed using a two-sublattic molecular field theroy(MFT).The MFT coefficients n FF ,n Rf and N RR are obtaines. According to the MFT coefficients, T FF , F RF , T RF ,the contributions to T c due to FeFe,RR and RF interationsare calculated for these compounds. |
