Analysing on ultrafine structure of (PrNd)<sub><italic>x</italic></sub>Al<sub>0.7</sub>Nb<sub>0.6</sub>Cu<sub>0.1</sub>B<sub>1.05</sub>Fe<sub>97.55-<italic>x</italic></sub> alloy by high pressure
Abstract
(PrNd)<sub><italic>x</italic></sub>Al<sub>0.7</sub>Nb<sub>0.6</sub>Cu<sub>0.1</sub>B<sub>1.05</sub>Fe<sub>97.55-<italic>x</italic></sub> alloy was produced by general and high pressure molding. Its magnetic properties and ultrafine structure were researched contrastively via vibrating specimen magnetometer, Mossbauer spectroscope, electron spin-resonance spectroscopy spectrometer. It was showed that value of <italic>H<sub>cj</sub></italic> and (<italic>BH</italic>)<sub>max</sub> of samples by 1.8 GPa and 3.6 GPa pressure are increased 133, 120.3 kA m<sup>-1</sup> and 0.6, 3.2 kJ m<sup>-3</sup>. B-rich and α-Fe phases of samples via high pressure are less than those of sample via general pressure. On the other hand, intrinsic symmetry of other atoms is changed and g factor is increased. <italic>H</italic><sub>in</sub> of samples via 0.2, 1.8, 3.6 GPa pressure is 277.12, 277.04 and 275.66 kOe respectively.
