Magnetocaloric effects and magnetic regenerator performances in metallic glasses

Abstract

Metallic glasses with functional properties, such as magnetic properties, are promising materials for potential applications and have aroused great interest. Magnetic phase transition is an important feature of metallic glass. The unique effect of the magnetic phase transition can be applied to the field of refrigeration. On the one hand, due to its magnetocaloric effect, the amorphous alloy can be used as a magnetic refrigeration material for magnetic refrigerator. On the other hand, because of its specific heat anomaly the amorphous alloy can be used as a magnetic regenerator material for cryogenic refrigerator. In recent years, the magnetocaloric effects and magnetic regenerator performances of metallic glasses have become hot topics in the field, and opened up possibilities for the functional applications of metallic glasses. In this paper, the principle of magnetocaloric effect and magnetic regenerator performance of metallic glass and its characteristics and application prospect are introduced in detail.
