Abstract
Provided is a magnetic refrigeration material whose magnetic transition temperature has been adjusted with high accuracy and which includes at least a first predetermined magnetic refrigeration material and a second predetermined magnetic refrigeration material which differs from the first magnetic refrigeration material. The absolute value of the difference between the magnetic transition temperature of the present magnetic refrigeration material and a target magnetic transition temperature is 0.7 K or less. The content of the first magnetic refrigeration material and the content of the second magnetic refrigeration material are determined by the magnetic transition temperatures of the first magnetic refrigeration material and the second magnetic refrigeration material and by a target magnetic transition temperature of the magnetic refrigeration material.
