研究了Gd0 6Tb0 4-xCox 系列稀土合金在 2 6 1～ 2 90K温区范围的磁熵变 ,发现这种合金具有较大的磁熵变值 ,适合作为中低磁场 (1～ 2T)下的室温磁制冷材料。
The magnetic entropy change of Gd0 6Tb0 4-xCox series rare earth alloys in the temperature range of 2 6 1 ~ 2 90K was studied. It was found that this alloy has a large magnetic entropy change value, which is suitable for the low and medium magnetic fields (1 ~ 2T) Room temperature magnetic refrigeration materials.
