摘要: The regenerating material according to the present invention comprises two alloy phases which differ in a content of rare earth elements. Of these alloy phases, a dominant phase in the regenerating material is defined as a main phase, and the other phase is defined as a sub-phase. A plurality of particles, each of which consists of a granular main phase and a sub-phase present on the surface of the main phase, gathers to form an aggregate. Otherwise, a sub-phase present in a main phase in the form of fiber. The refrigerator according to the present invention comprises a regenerator charged with above-mentioned regenerating material, a coolant gas and an expansion means for expanding the coolant gas.

摘要: The present invention provides a regenerative material having a peak specific heat at a low temperature. The material is made of a solid solution of at least two different magnetic type metal compounds, for example, ferromagnetic Er.sub.3 Co and antiferromagnetic Er.sub.3 Ni. From these compounds, the regenerative material Er.sub.3 (Ni,Co) in solid-solution form is produced and the material has a lower magnetic phase transition point than each of the compounds. The regenerative material is utilized for a regenerator of a refrigerator.
