Fig. 3: Exploring Re1−xMox superconductivity via TF-μSR.
From: Re1−xMox as an ideal test case of time-reversal symmetry breaking in unconventional superconductors
a, b, c, d TF-μSR time spectra, collected in the superconducting and in the normal state (i.e., below and above Tc), of different phases of Re1−xMox alloys with x = 0 (hcp-Mg) (a), x = 0.23 (α-Mn) (b), x = 0.45 (β-CrFe) (c), and x = 0.60 (bcc-W) (d). e, f, g, h Fast Fourier transforms (FFT) of the time spectra shown in the left panels for x = 0 (e), x = 0.23 (f), x = 0.45 (g), and x = 0.60 (h). The upper and lower panels represent FFT in the superconducting and normal states, respectively. Clear diamagnetic shifts and field distribution broadening are observed in upper panels (superconducting state). The vertical dashed lines indicate the applied magnetic field in each case, always larger than the respective lower critical field value (see Supplementary Fig. 3 and Supplementary Table 1). Solid lines through the data are fits to Eq. (2). Panels b and f refer to the x = 0.23 (α-Mn) sample, synthesized via solid-state reaction. The sample prepared via arc melting exhibits similar features (see Supplementary Fig. 5). The temperature-dependent diamagnetic shifts are shown in Supplementary Fig. 6.
