Dataset for "Polarization-resolved measurement of forward volume spin waves by micro-focused Brillouin light scattering"

This dataset contains the data for the publication "Polarization-resolved measurement of forward volume spin waves by micro-focused Brillouin light scattering" together with the useful files used to obtain the Cotton-Mouton constant and the SpinWaveToolkit package (see SpinWaveToolkit on GitHub) in the version used to prepare the analysis. Folder 'BYIG-100nmthickness' contains experimental data in HBF5 files together with the numpy.array and SVG graphics of the chosen modes taken from the spectra, which are used in further analysis. Folder 'Figures' contains all figures and Jupyter notebooks used to generate the figures. Folder 'modelling-data' contains numpy.array and SVG graphics of the chosen modes from the semi-analytical calculations. Jupyter notebook 'experiment-maps.ipynb' was used to analyze the experimental spectra and obtain the relative angle between the polarizer and analyzer. Jupyter notebooks 'fitting-BVDE.ipynb' and 'fitting_FV.ipynb' were used to fit the values of the Cotton-Mouton constants using semi-analytical model based on the experimental results.本数据集配套于学术论文《基于微聚焦布里渊光散射的正向体自旋波偏振分辨测量》，包含了用于获取科顿-穆顿常数（Cotton-Mouton constant）以及本次分析所用版本的SpinWaveToolkit软件包的相关辅助文件（可于GitHub平台查阅该SpinWaveToolkit）。 文件夹"BYIG-100nmthickness"内存储了HBF5格式的实验数据，以及从光谱中提取、用于后续分析的选定自旋波模式的numpy数组与SVG矢量图形。 文件夹"Figures"收纳了所有用于生成实验图表的图像文件及Jupyter笔记本代码。 文件夹"modelling-data"包含了通过半解析计算得到的选定自旋波模式的numpy数组与SVG矢量图形。 Jupyter笔记本"experiment-maps.ipynb"用于分析实验光谱，以获取偏振器与检偏器之间的相对夹角。 Jupyter笔记本"fitting-BVDE.ipynb"与"fitting_FV.ipynb"则基于实验结果搭建半解析模型，用于拟合科顿-穆顿常数的数值。
