Abstract :
The Gd2Fe14-xMxC compounds form solid solutions in the composition ranges x⩽1.0 for-M=Cu or V and x⩽1.5 for M=Si or Ni. The Curie temperatures increase when Fe is replaced by Ni, Cu and Si and decrease when this is substituted by V. The above behaviour is correlated with site occupancy of substitutional elements in P4√mnm-type lattice. The decrease of magnetizations, at 4.2 K as result of substitutions, is greater than that expected from simple dilution behaviour. The magnetic data are analysed in correlation with those obtained in corresponding borides
