The present work is designed to investigate the impact of shock waves on Zinc Ferrite nanoparticles (ZnFe₂O₄) NPs. The test material was prepared by precipitation method and shock wave recovery experiment is done by tabletop pressure driven shock tube. The shock wave induced changes in structural, morphological and magnetic properties are noticed by various analytical techniques such as powder X-ray Diffractometer (PXRD), fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and vibrating sample magnetometer (VSM) and the obtained PXRD results shows no significant structural changes. Switchable paramagnetic to superparamagnetic behaviour is observed during the shock wave loaded conditions. The mechanism of shock wave induced magnetic phase transition is discussed.

冲击波诱导的ZnFe 2 O 4铁氧体纳米粒子的可转换磁性相变行为

本工作旨在研究冲击波对锌铁氧体纳米颗粒（ZnFe ₂ O ₄）NP。试验材料采用沉淀法制备，冲击波恢复实验采用台式压力驱动激波管进行。各种分析技术都可以注意到冲击波引起的结构，形态和磁性的变化，例如粉末X射线衍射仪（PXRD），傅立叶变换红外光谱仪（FTIR），扫描电子显微镜（SEM）和振动样品磁强计（VSM） ），所得PXRD结果显示无明显结构变化。在冲击波加载条件下观察到顺磁性到超顺磁性的切换。讨论了冲击波引起的磁相变的机理。
