Abstract
A first-stage regenerator material and a second-stage regenerator material are regenerator materials each having a laminated structure for use in a GM refrigerator. Each layer of the regenerator material is provided with a plurality of holes to allow gas to pass therethrough along a laminating direction. At least one layer includes a base material and a coating covering the base material. Volumetric specific heat of the coating is larger than volumetric specific heat of the base material in a temperature range from 20 K to 40 K.
