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 Dy₂Ti₂O₇in 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.
