摘要: Abstract We explored the possibility of Pr-Fe-B and (Pr0.75Ce0.25)-Fe-B based hot-deformed magnets as magnetic field source for cryogenic refrigeration. Thanks to elimination spin reorientation effect in rare earth (RE)-Fe-B system, magnet shows a large remanence µ0Mr = 1.75 T with coercivity 7.4 at 20 K. To our surprise, even higher 1.76 4.8 The measured maximum energy product anisotropic is 612 kJ/m3 20 K, demonstrating their potential low-cost permanent applications.
