摘要

本研究的目的是研究用水热法合成的混合纳米晶氧化锌/氧化锰化合物的磁性能。这些化合物被设计为（ZnO）1−n（MnO）n，其中指数n的范围为0.05至0.60。报告了磁性测量的结果，包括作为温度（高达160 K）和频率（从7 Hz到9970 Hz）函数的交流磁化率，以及在高达9 T和高达50 K的磁场中的直流磁化率。根据MnO的标称重量含量，我们观察到了各种类型的磁性行为。MnO标称含量低（高达0.10）的样品在更高的温度下表现出居里-维斯行为。对于具有高标称重量贡献（从n=0.30到0.60）的样品，观察到自旋玻璃状或/和弱铁磁行为。

Hydrothermal Synthesis and Magnetic Properties of Zn/Mn Oxides Nano Particles

The aim of this study was to investigate the magnetic properties of mixed nanocrystalline Zn/manganese oxide compounds synthesized by a hydrothermal method. These compounds are designed as (ZnO)1−n(MnO)n, where index n ranges from 0.05 to 0.60. The results of magnetic measurements, including AC magnetic susceptibility as a function of temperature (up to 160 K) and frequency (from 7 Hz up to 9970 Hz), as well as DC magnetization in magnetic fields up to 9 T and temperature up to 50 K, are reported. We observed various types of magnetic behavior depending on the nominal weight content of MnO. Samples with a low nominal content (up to n = 0.10) of MnO exhibited Curie–Weiss behavior at higher temperatures. For samples with high nominal weight contribution (from n = 0.30 to 0.60), spin-glass-like or/and weak ferromagnetic behavior is observed.
