摘要
本文根据高温磁致冷冻工作介质的特点,用铁磁性分子场理论定量地考察了工作介质的磁熵随外加磁场和温度的变化规律,给出了选择适宜工作介质的方法。
The dependence of magnetic entropy of high temperature magnetic refrig-erator medium on the strength of external magnetic field and on the temperature is quantitafively investigated by means of ferromagnetic molecular field theory. A criterion for appropriately selecting working substances is presented.
