Dataset and software for "Experimental observation of vortex rings in a bulk magnet"

The dataset and codes for the manuscript: "Experimental observation of vortex rings in a bulk magnet" Nature Physics (2020) Contains: - Reconstruction of the magnetisation for the three magnetic configurations presented in the paper, in both .mat and .vtk format, for analysis and visualisation with matlab and paraview. - Analysis codes for the calculation of the magnetic vorticity from the magnetisation - Paraview state files for the visualisation and analysis of the configurations.本数据集与配套代码对应发表于《Nature Physics》2020年的论文《体磁体中涡旋环的实验观测》（*Experimental observation of vortex rings in a bulk magnet*）。包含以下内容： - 论文中提及的三种磁构型的磁化强度重构数据，格式为.mat与.vtk，可通过MATLAB与Paraview进行分析与可视化。 - 用于从磁化强度计算磁涡度的分析代码。 - 用于各磁构型可视化与分析的Paraview状态文件。
