Five heavy lanthanide ferromagnetic intermetallic compounds were studied as potential magnetic refrigerants for the liquefaction of hydrogen gas. (Dy{sub 0.5}Er{sub 0.5})Al{sub 2} and TbNi{sub 2} appear to be better refrigerants than GdPd for a Joule-Brayton cycle refrigerator, while (Gd{sub 0.54}Er{sub 0.46})AlNi seems to be a suitable refrigerant for an Ericsson cycle refrigerator.
