Method for producing magnetic refrigeration material

Abstract

To provide a method for producing a magnetic refrigeration material, the method being capable of producing a magnetic refrigeration material that hardly undergoes deterioration in characteristics and has high corrosion resistance in a productive manner. The method for producing a magnetic refrigeration material of the present invention is characterized by including subjecting a powder of a magnetic refrigeration material containing a powder having a particle size of 150 μm or more and 500 μm or less to Cu electroplating in a plating liquid having a liquid temperature of 30°C or lower.
