摘要:

采用熔盐法合成了LaFeO3和GdFeO3多晶样品。研究了所得化合物的一些性质和质量。通过X射线衍射和Rietveld分析确定了样品的晶体结构和纯度。通过拉曼光谱和红外光谱对样品的振动性质进行了表征。穆斯堡尔谱用于确定Fe离子的离子状态和内部超精细磁场。在不损害化合物质量的情况下,实现了反应发生的热处理(温度和时间)的显著减少。

英文摘要:

Polycrystalline samples of LaFeO3 and GdFeO3 were synthesized by the molten salt method. Some properties and the quality of the resulting compounds were investigated. The crystal structure and purity of the samples was determined through X-ray diffraction and Rietveld analysis. The vibrational properties were characterized by Raman and IR spectroscopy. Mössbauer spectroscopy was used to determine the ionic state of the Fe ions and the internal hyperfine magnetic fields Considerable reduction of the heat treatment (temperature and time) for the reaction to take place was achieved without detriment of the quality of the compounds.
