Research data supporting "Unconventional superconductivity in the layered iron germanide YFe2Ge2"

Data is grouped according to the figures in the publication which it supports. Fig. 1 shows resistivity vs. temperature at various applied magnetic fields in YFe2Ge2, and the .txt datasets give the data underlying this diagram. Fig. 2 shows how resistive superconducting transition temperatures depend on sample quality, as measured by the residual resistance ratio, and the .txt dataset gives the underlying table of data. Fig. 3 shows heat capacity and magnetisation data taken at low temperature, and the .txt datasets give the underlying data, as well as giving the data underlying the theoretical extrapolation curves for temperatures less than 0.4 K. The inset to Fig. 3 shows the dependence of the critical field on temperature, as extracted from resistivity and heat capacity measurements, and the .txt datasets give the underlying data. Figure 1 in the Supplemental Material uses some of the same data as Fig. 3. Methods are described further in the publication.
