The (Dy{sub 1-x}Er{sub x})Al{sub 2} alloys as active magnetic refrigeration
- Ames Lab., IA (United States)
The low temperature properties (heat capacity from 3 to 350 K in fields up to 10 T, and both ac magnetic susceptibility and dc magnetic susceptibility and magnetization from 4 to 325 K in dc fields up to 5.5 T) of nine (Dy{sub 1-x}Er{sub x})Al{sub 2} alloys have been studied as potential active magnetic regenerator (AMR) materials for hydrogen liquefaction using magnetic refrigeration. These data indicate that the (Dy{sub 1-x}Er{sub x})Al{sub 2} alloys would make excellent AMR materials, especially the combination (Dy{sub 0.4}Er{sub 0.6})Al{sub 2} plus DyAl{sub 2} phase mixture, which is significantly better than the prototype (Dy{sub 0.5}Er{sub 0.5})Al{sub 2} plus GdNi{sub 2} phase mixture currently being tested. In addition, the magnetic phase diagram of the (Dy{sub 1-x}Er{sub x})Al{sub 2} has been determined.
