高温原位磁化率测试法利用顺磁性材料在相变时磁化率变化的原理,直接测试出材料相变时的转变温区,是研究顺磁性材料相变的一种新的尝试.我们采用高温法拉第磁秤测试了Ag2O和CuO在升温和降温中磁化率的变化曲线,通过磁化率的转变演示了Ag2O和CuO相变的动态过程.以此介绍了原位观测顺磁性材料晶体学相变的高温法拉第磁秤方法.高温法拉第磁秤在相变研究上的应用为顺磁性材料制备工艺提供了真实可靠的实验参数.
High temperature in-situ magnetic susceptibility testing method The use of paramagnetic materials in the phase change magnetic susceptibility changes, the direct test of the transformation phase transition temperature of the material is to study the phase transition of paramagnetic materials a new attempt. We use high temperature Faraday magnetic scale tests the change of magnetic susceptibility of Ag2O and CuO during heating and cooling, and demonstrates the dynamic process of the phase transition of Ag2O and CuO by the change of magnetic susceptibility. In this paper, the in situ observation of the phase transition of the paramagnetic material High temperature Faraday magnetic scale method.The application of high temperature Faraday magnetic scale in phase change research provides a reliable and reliable experimental parameter for paramagnetic material preparation process.
