Ternary Dy-Er-Al magnetic refrigerants

摘要

A ternary magnetic refrigerant material comprising (Dy.sub.1-x Er.sub. x)Al.sub.2 for a magnetic refrigerator using the Joule-Brayton thermodynamic cycle spanning a temperature range from about 60K to about 10K, which can be adjusted by changing the Dy to Er ratio of the refrigerant.
