Abstract

Sintered Nd17 (Fe1−x Cox)75B8 permanent magnetic alloys have been studied by Mössbauer effect, X-ray diffraction and electron probe micro-analysis, The results show that the alloys are composed of the tetragonal phase Nd2(Fe,Co)14B, the B-rich phase Nd111(Fe,Co)4B4 and the Nd-rich phase Nd80(Fe,Co)19B. In the tetragonal phase, Co atoms occupy preferentially the k2 and j2 sites, and Fe atoms occupy randomly the k1 site and preferentially the j1 site while the e and c sites seem to be completely occupied by Fe atoms.
