摘要：

We have investigated the crystal structure and magnetic properties of novel ternary compounds of the composition R2(Fe0.91V0.09)17 (R = Y, Nd, Sm, Gd). X-ray diffraction showed that their crystal structure is a superstructure of a new type based on the CaCu5 structure, but with lattice parameters five times larger than those of CaCu5. The Curie temperature and saturation magnetization of the compounds studied fall into the ranges 440-520 K and 15-30-mu(B) (fu.)-1 at 4.2 K respectively. The influence of dissolved cobalt, carbon and nitrogen on the magnetic properties of the compounds R2(Fe0.91V0.09)17 has been studied.
