Magnetic susceptibility data for the paper: Power spectrum of magnetic relaxation in spin ice: Anomalous diffusion in a Coulomb fluid

To perform the analysis of magnetic noise in the spin ice sample Dy2Ti2O7 in the temperature regime 2K to 28K magnetic susceptibility data needs to be obtained. This dataset contains the mass susceptibility data. Specifically the data were all taken in zero applied magnetic field, with the excitation field along the 111 axis. Each data file is organised in the form of x,y,z where x is the frequency (Hz) and y and z are the real and imaginary part of the mass susceptibility (in SI units). The format of the file name is "axis_field_temperature_combined" where axis is the 111, field is 0 T and the temperature is the variable, combined simply means combing data from two different instruments. The mass of the sample 33.7mg, with a demagnetization value of 0.37. It is possible to transform the susceptibility data into noise with this information assuming the data is in the linear response regime and at equilibrium.

为开展温度区间2K至28K内的自旋冰（spin ice）样品Dy₂Ti₂O₇的磁噪声分析，需获取磁化率数据。本数据集包含质量磁化率相关数据。具体而言，所有测量均在零外加磁场条件下完成，激励场沿[111]晶轴方向。每份数据文件均采用x、y、z的格式组织：其中x为频率（单位：Hz），y与z分别为质量磁化率的实部与虚部，单位采用国际单位制（SI）。文件名遵循"axis_field_temperature_combined"的格式，其中axis指代[111]晶轴，field为0 T，temperature为变量项，combined表示该文件整合自两台不同仪器的测量数据。样品质量为33.7 mg，退磁因子为0.37。若数据处于线性响应区间且满足平衡态条件，则可通过上述信息将磁化率数据转换为磁噪声数据。
