Title:
MAGNETOCALORIC ALLOY AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/204372
Kind Code:
A1
Abstract:
The present invention provides a method for preparing a magnetocaloric alloy that has a high magnetic entropy change value and excellent cooling efficiency, thus having high relative cooling efficiency, and has a Curie temperature (Tc) near room temperature, and thus can easily be applicable to room-temperature cooling systems and the like. This enables to prepare a magnetocaloric alloy having a uniform composition.
