Fig. 1: Results of the μ⁺SR analysis for LiCrSe₂.

a Weak transverse field (wTF) μ⁺SR time spectra at the selected temperatures 100 K (open orange circles), 29 K (open gray circles), 24 K (open blue circles). The best fit to the data (corresponding to the function in Eq. (1)) is shown as solid lines. b Temperature dependence of the wTF asymmetry (filled red circles), the continuous red line represents a fit to a sigmoid function giving the AFM transition temperature T_N = 29.11 ± 0.06 K. c, d Zero-field (ZF) μ⁺SR time spectrum at T = 2 K (open black circles) with the fit to Eq. (2) (solid magenta line) shown in (c) long and (d) short time domain, respectively. e Fast Fourier Transform (FFT) of the spectrum and its fit shown in (d). f ZF muon time spectra at selected temperatures T = 25 K (orange open circles), 28.5 K (light blue open circles) and 29.2 K (purple open circles) in the short time domain. The spectra are shifted along the y-axis for clarity of display. The black continuous lines are fits to Eq. (2). g, h Temperature dependencies of the ZF fit parameters extracted from Eq. (2) for the two oscillating components of the signal (green and red filled circles) plus the slow tail component (blue filled circles). The error bars in the plot represent the confidence intervals of the reported values.
