Abstract
The temperature dependence of magnetization is analysed for R2Co17 via the two-sublattice molecular field theory. The molecular field coeffi cients n(CC), n(RC) and n(RR) are obtained, by which T-c was calculate d. Using the least-squares method, the fitted-form of H-R(T) varying w ith temperature for each compound are presented. The results are analy sed and compared with the results obtained from the Fe-based compounds . In addition, the parameters F = M-Co(2)(0).n(CC)/T-c are calculated for each R2Co17 and by F, some unexpected phenomena hitherto unobserve d are explained.
