摘要: In this work we report the magnetic and structural properties obtained by Mossbauer spectrometry, Vibrating Sample Magnetometer X-ray diffraction of milled powders with initial composition Nd2(Fe100−x Nbx)14B x = 0 4. The mixtures were ball for different times up to 240 h. Structural microstructural parameters derived from high statistics patterns discussed as a function milling time. spectra samples fitted means sextet an hyperfine field distribution, associated pure iron phase (α-Fe) disordered iron-based phase, respectively. α-Fe grain size decreases 50 nm 6 h 5 results allow conclude that these behave soft ferromagnets.
