A coupling model of the pluralistic magnetic component R-T intermetall
ic compounds (R denotes rare earth, T denotes transition metal) has be
en proposed by means of the mean-molecular-field analysis. Using the m
odel, the Curie temperature T-c of (Sm1-xPrx)(2)Fe-17 compounds has be
en calculated and the calculated values have been compared with the ex
perimental values. It is found that the former are consistent with the
later. (C) 1994 American Institute of Physics.
