Аннотация:
A combined nuclear magnetic resonance and Mossbauer spectroscopy study has been performed to investigate the effect of Y substitution on the phase composition of crystallized Nd<sub>4</sub>Fe<sub>77.5</sub>B<sub>18.5</sub> alloy. The annealing temperature dependence of the phase components for Y<sub>4</sub>F<sub>77.5</sub>B<sub>18.5</sub> was studied as well. It was shown that the substitution of Y has a different effect on the phase components from that of Gd substitution in some cases. A full substitution of Y results in the appearance of a new metastable phase Y<sub>3</sub>Fe<sub>62</sub>B<sub>14</sub>.
