Abstract :
The effect of carbon substitution on the magnetic properties of Nd 2Fe13.8Mo0.1Nb0.1B1-x Cx (with x=0, 0.2, 0.4, 0.6, 0.8) was studied. The anisotropy field was measured from 77 K to 379 K using the singular point detection technique. It was found that both the anisotropy field and the critical field increase with increasing carbon content. A slight decrease of both Curie temperature and saturation magnetization were observed. The increase of anisotropy field may be due to a variation of the crystal field behavior due to Nd ions when boron is substituted by carbon. The increase of critical field with increasing carbon content may be due to the variation of high-order crystalline electric field terms
