Abstract In this work, the method of quantitative ferrite phase control, which is based on thermomagnetometric analysis of the ferrite samples in magnetic field, was developed. The magneto-phase transitions in LiZn and LiTi ferrites with chemical formulas Li0.5(1x)Fe2.50.5xZnxO4 and Li0.5(1+x)Fe2.51.5xTixO4 were studied, and their phase compositions were analyzed by both the developed method and X-ray diffraction analysis. It was shown that the thermomagnetometry method compared to X-ray diffraction analysis allows to examine more precisely the magnetic phases in synthesized ferrites with inhomogeneous phase composition. However, a complex analysis, using both X-ray and thermomagnetometry methods, will be the most optimal in case of the formation of non-magnetic and poor magnetic phases.

通过 XRD 和热磁分析法分析 LiZn 和 LiTi 铁氧体的相组成

摘要 在这项工作中，开发了一种基于铁氧体样品在磁场中的热磁分析的定量铁氧体相位控制方法。研究了化学式为 Li0.5(1x)Fe2.50.5xZnxO4 和 Li0.5(1+x)Fe2.51.5xTixO4 的 LiZn 和 LiTi 铁氧体的磁相转变，并通过两种方法分析了它们的相组成和 X 射线衍射分析。结果表明，与 X 射线衍射分析相比，热磁法方法可以更精确地检查具有不均匀相组成的合成铁氧体中的磁相。然而，在形成非磁性和弱磁性相的情况下，使用 X 射线和热磁测量方法的复杂分析将是最佳选择。
