（Er0.65Ho0.35）（In0.9Sn0.1）3的低温比热性能

The specific heat propertities of （Er0.65Ho0.35）（In0.9Sn0.1）3 at low temperature

比热行为对蓄冷式制冷机中使用的蓄冷材料是非常重要的，为了寻找在5K附近使用的新型磁性蓄冷材料，研究了伪二元化合物（Er0.65Ho0.35）（In0.9Sn0.1）3从2～40K温度范围内的比热行为。发现（Er0.65Ho0.35）（In0.9Sn0.1）3在5．96K出现较高比热峰，使之具有比较大的低温热容。

Specific heat is important to regenerator materials in regenerator refrigerater. In order to find new regenerator materials around 5K, the specific heat of pseudobinary compound （Er0.65Ho0.35）（In0.9Sn0.1）3 from 2 to 40K have been investigated. There is a specific heat peak at 5.96K, and it makes the pseudobinary compound have large heat capacity at low temperature.
