<p>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 Er3Co and antiferromagnetic Er3Ni. From these compounds, the regenerative material Er3(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. <IMAGE></p> |
