Abstract
The Mossbauer spectra of Nd2Fe14B and Nd2(Fe1−xCox)14B compounds (x=0.0.05, 0.10 and 0.16) have been investigated at room temperature and at 77 K. Taking advantage of combined ME and NMR investigations of the Nd2Fe14B compund, the hyperfine field values and their assignment to the six Fe sites have been determined to be the following sequence: 378(j2), 346(k2), 334(j1), 325(k1), 322(c), 306(e) kOe. The substitution of Co for Fe decreases the hyperfine fields at all Fe sites. The intensity variations of the subspectra with Co content show that Co atoms have a strong preference to occupy the k2 site, but have a rather less tendency to enter the j2 site, which is preferred by Fe atoms.
