摘要
Samples of RFe(10)V(2)C(x) with R = Y, Gd, Dy or Er were prepared by are melting. X-ray diffraction and thermomagnetic analyses showed that interstitial carbides with the ThMn12 structure can be formed only for a small amount of C (x less than or equal to 0.3). The effects of C addition on lattice expansion and Curie temperature are much smaller in the carbides prepared by are melting than in those prepared by gas-solid reaction. Neutron diffraction shows that the C atoms occupy the interstitial site in the structure.
