Abstract

Four samples of Nd₂Fe₁₇M_xC_y (where M = Al, Ga, Ti, V) were synthesized using rf induction melting and C was introduced from the melt. Structural studies were then carried out using neutron diffraction. All samples were confirmed to have the Th₂Zn_17-type rhombohedral structure with expanded unit cell volumes. However, the volume effect, as well as the site preference of the substitutional atoms (M) is different among these samples and is different compared to their uncarbided counterparts. the C atoms were found to reside in the 9e site for all samples. The observed Curie temperature is higher for samples with higher C concentrations.
