Abstract

Self-consistent spin-polarized electronic structure calculations have been carried out to derive the magnetic properties of the Sm2Fe17-xAx (A=Al, Ga, Si and x=0 and 1). The influence of impurities on the Curie temperature (TC) of Sm2Fe17 has been studied using the spin-fluctuation approach of Mohn and Wohlfarth. The calculated TC generally goes up with the addition of each impurity but the relative increase in TC depends on the type of the impurity and its site. The calculated TC enhancement weighted with the impurity-site occupancy from Mössbauer data are in good agreement with the experimental data.
