Study of the magnetite to maghemite transition using microwave permittivity and permeability measurements

This dataset contains the calculated effective dielectric and magnetic properties of annealed magnetite using the microwave cavity perturbation method. It also includes the data points for the X-ray photoelectron spectroscopy, X-ray diffraction and vibrating sample magnetometry traces shown in the paper, which indicates the phase change of the material to provide insight into the microwave measurements.本数据集包含采用微波腔微扰法（microwave cavity perturbation method）测得的退火磁铁矿的有效介电与磁性能计算数据。此外，数据集还涵盖论文中展示的X射线光电子能谱（X-ray photoelectron spectroscopy）、X射线衍射（X-ray diffraction）与振动样品磁强计（vibrating sample magnetometry）测试曲线的相关数据点；上述表征数据可揭示材料的相变过程，从而为微波测量结果的分析提供参考依据。
