摘要/Abstract

摘要： 本文研究了Li-Ti系尖晶石型铁氧体中⁵⁷Fe的核磁共振(77K-室温)和室温穆斯堡尔效应。观测到磁亚点阵引起的核磁共振多线谱,讨论了共振频率随温度和成分的变化,及其与饱和磁矩的关系。近纯Li铁氧体和用Ti、Mg、Zn非磁性离子代换的复合铁氧体的穆斯堡尔谱可分别分解为2组和7组亚谱,讨论了所得到的实验结果。

Abstract: The ⁵⁷Fe nuclear magnetic resonance (NMR)(77K-room temperature RT) and RT Mossbauer effect(ME) of Li-Ti-Mg and Li-Ti-Zn fervite systems waseve studied in this work.The NMR multiple line spectra caused bymagnetic sublattice were observed, the temperature and compositionalvariations of resonant frequences and their dependences on saturationmagnetic moment were discussed. The Mossbauer spectra of nearly Pure Li-ferrite and complex ferrites substituted by Ti,Mg and Zn ions may be resolved into 2 and 7 sets of subspectra, respectiyely.The experiment results were discussed.
