摘要: Abstract The hydrogenation effect on the hysteresis properties of rapidly quenched (RQ) (Nd 0.55 Ho 0.45 ) 2.7 (Fe 0.8 Co 0.2 14 B 1.2 compound obtained by melt-spinning is studied. A comparative study RQ alloy and its hydride H 2.5 has shown that resulted in increase magnetization without significant Curie temperature. In contrast to hydrogen-free having a maximum c ( T curve, hydrogen-charged increased monotonously with decreasing Among factors affecting hydrogenated sample are grain size crystalline phase decrease both iron rare earth contributions magnetocrystalline anisotropy. High-field hysteretic distortions magnetization/demagnetization curves RQ + hydrogen samples observed at 4.2 K fields up 90 kOe indicating existence magnetic very high local coercivity.
