Extended Data Fig. 3: Testing different backgrounds.
From: Split superconducting and time-reversal symmetry-breaking transitions in Sr2RuO4 under stress
a, A(t) resulting from the single histogram analysis of Sample D at − 0.43 GPa under different assumptions about the background: non-relaxing, and with 55% of the background muon spins taken to relax following the relaxation function of copper. b, Results from the single histogram analysis for the relaxation rate λ taking different portions of copper in the background. c, Data in panel (b) with temperature independent constants subtracted. Assuming different backgrounds is seen to have essentially no effect on temperature-dependent relative changes in λ extracted from analysis. d, Fourier transforms of the transverse-field μSR time spectra of Sample A2 above and below Tc. e, Comparison of the temperature dependence of the zero field muon spin relaxation rate (left scale) and the specific heat data (right scale) for Samples A and A2.
