摘要
简述了磁熵概念及磁熵变测量原理,介绍了应用于教学的磁熵变测量实验装置.利用该装置测量了金属钆在0～50℃温度范围,最大磁场为2T的等温磁化曲线,计算了不同温度下的磁熵变.
Based on the principles of magnetic entropy, the measurement method of magnetic entropy change was introduced. A magnetic entropy measurement device for teaching was made. Using this device, the magnetic entropy of Gd was measured from 0-50 ℃, under the maximum magnetic field of 2T.
