我们开发了一种能够在高达 5 T 的外加磁场下工作的差示扫描量热计。该量热计灵敏度很高，工作温度范围为 10-300 K。结果表明，经过适当的校准后，该系统能够测定一级固-固相变中的潜热和熵变。该系统对于研究因磁结构相变而表现出巨磁热效应的材料特别有用。给出了 Gd5(Si0.1Ge0.9)4 的数据。
We have developed a differential scanning calorimeter capable of working under applied magnetic fields of up to 5 T. The calorimeter is highly sensitive and operates over the temperature range 10–300 K. It is shown that, after a proper calibration, the system enables determination of the latent heat and entropy changes in first-order solid–solid phase transitions. The system is particularly useful for investigating materials that exhibit the giant magnetocaloric effect arising from a magnetostructural phase transition. Data for Gd5(Si0.1Ge0.9)4 are presented.
