Normal-state transport properties of (Li_1−xFe_x)OHFe_1−ySe under high pressure. a A double-logarithmic plot of (ρ − ρ₀) vs. T illustrating the variation with pressure of the normal-state resistivity from the Fermi-liquid ρ ~ T² for P < 5 GPa to non-Fermi-liquid ρ ~ T^1.5 behavior for P > 6.5 GPa. Except for the curve at 5 GPa, all other curves have been vertically shifted for clarity. Field dependence of b the magnetoresistance MR and c the transverse resistivity ρ_xy at the normal state just above T_c under various pressures. The Hall coefficient R_H is determined from the field derivative of ρ_xy, R_H ≡ dρ_xy/dH, at each pressure
