摘要
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。
A series of alloy Gd 0.6 Tb 0.4-x Co x(x=0,0.05,0.1,0.15)were studied at temperatures between 261～290K under a magnetic field up to 1.5T.We found that with giant magnetic entropy change the alloys are suitable for making room temperature magnetic refrigeration material at low magnetic field(1～2T).
