WebThe Mössbauer spectra of Pr 2 Fe 14 B and Gd 2 Fe 14 B have been measured from 85 to 295 K and fit with a second order approximation in which the angle, ϕ, between the principal axis of the electric field gradient and the easy-axis of magnetization has been fixed by the positions of the near-neighbor rare-earth atoms. WebSpherical inclusions in the size range of 500 Å-l μm have been observed inside the matrix Re2Fe14B grains. Characterization by X-ray diffraction, electron microdiffraction and energy dispersive X-ray microanalysis, shows that these inclusions are f.c.c. rate earth oxides. The volume fraction of these inclusions increases with Ho content.
