Fig. 4: Muon spin rotation in superconducting H2TiSe2.
a, b Zero-field cooling transverse-field muon-spin polarization PTF(t) in a 14-mT magnetic field applied parallel to the ab planes, (a), or in a 10-mT field applied parallel to the c-axis, (b). Solid lines are fits to the model described by Eq. (4). The error of the positron count for each bin is its standard deviation, while the error bars of each bin in PTF(t) are calculated by error propagation. c Temperature dependence of the depolarization rate (red circles) in a magnetic field μ0H = 10 mT, applied parallel to the c axis. Note the lack of saturation at low temperatures. The dark-blue square represents the depolarization rate recorded after field cooling in the same applied magnetic field. The gray dashed line represents the average nuclear dipolar contribution, here, σn = 0.32 ± 0.02 μs−1. The error bars are the standard deviation of the fit parameters.
