Fig. 4: Phase diagram and the low-temperature resistance analysis.

a Phase diagram of 5% Hg-doped CeRhIn₅ under pressure. Color represents the in-plane resistance. The violet and magenta symbols indicate the magnetic transitions T_N and T_M, respectively, which were determined from resistance inflection points. The red symbols denote the Fermi-liquid (FL) temperature, below which the resistance follows a FL behavior as R = R₀ + AT². b Pressure dependence of the residual resistance (violet diamonds, left y-axis) and the A coefficient (red balls, right y-axis) obtained from the fits of R = R₀ + AT². P_c1 is the lower critical pressure where T_N extrapolates to zero temperature, while P_c2 is the higher critical pressure at which T_M is suppressed, and the system enters a FL state. The dashed lines are guides to the eyes. AFM1 and AFM2 correspond to two different magnetic phases. FL represents the Fermi-liquid regime. The squares and circles represent the transition temperatures obtained from different runs. c–f Non-Fermi-liquid behavior in the vicinity of two critical pressures. The red solid lines are least-squares fits to the form R = R₀ + A^*Tⁿ.
