Description

Magnetization measurements on the Sm2Fe17Cx and Er2Fe17Cx (x = 0, 0.5, 0.8 or 1.0) intermetallic compounds are reported at different temperatures. On the basis of a two-sublattice model the data have been analyzed using the molecular-field theory. The molecular-field coefficients nFF, nRF, nRR and spin-exchange parameters AFF, ARF, ARR for these two series have been derived. The results of the analysis showed that with increase of x, the pronounced enhancement of nFF or AFF leads to the increase of the Curie temperature (Tc) of the compounds. The data were compared with previous ones and discussed. (orig.)
