We apply the extended s-f model to magnetic pseudobinary alloys. We calculate the Curie temperature and magnetic moment in the paramagnetic state as functions of concentration x. The calculated quantities are in good agreement with the quantities experimentally measured for Eu1-xGdxS, Eu1-xGdxSe, RexGd1-xAl2 (Re = Dy, Ho, Er, La, Lu, Y), Gd(Al1-xMex)2 (Me = Cu, Ag, Pd, In, Sn),... |
