摘要
介绍综合热分析仪Diamond TG/DTA在磁性材料研究中的应用.提出在外加磁场作用下,得到样品的热重曲线(TG),由TG曲线分析样品磁性相变及样品居里温度变化的原因,看到稀土铁基金属间化合物样品替代的Co元素的站位和元素之间相互作用对居里温度有很大影响.作为一种测量居里温度的方法,拓展Diamond TG/DTA热分析仪应用研究领域.
The application of a comprehensive thermal analyzer Diamond TG/DTA in the research of magnetic material is introduced. Under the action of magnetic field, thermogravimetric curves （TG） of the samples were obtained. From the analysis of the TG curve of the magnetic phase transition of sample and the cause of the Curie temperature change, it is seen that positioning of the replaced Co element on the rare earth iron compound sample and the interaction between the elements have great impact on the Curie temperature. As a measuring method for Curie temperature,it expands the field of application and research for Diamond TG/DTA.
