摘要
本文考察了低磁场（１特斯拉）４ｆ稀土元素Ｇｄ的二元系金属间化合物的磁热效应。发现部份Ｇｄ的二元系化合物具有优异的磁热效应及室温附近的铁磁－顺磁转变居里温度，非常适合作为低磁场室温磁致冷工作介质材料。
The magnetocaloric effects on binary gadolinium intermetallics have been ex-perimentally investigated by applying the sample with low magnetic field(～1T ) underadiadatic condition,It is shown that some binary gadolinium intermetallics ,with bothexcellent magnetocaloric effects and a lower ferromagnetic-paramagnetic curie tempera-ture than 293 K,are suitable working substances of room temperature magnetic refrig-eration.
