(color online) Temperature–pressure phase diagrams obtained at different magnetic fields for Ca_0.73La_0.27FeAs₂ single crystals. The acronyms PM, AFM, and SC stand for paramagnetic, antiferromagnetic, and superconducting phases, respectively. The magenta-colored circles and custom diamonds represent the temperature of the AMF phase transition detected from two-run electrical resistance measurements (T_M(R-1) and T_M(R-2)) and heat capacity T_M(C) measurements under hydrostatic pressure conditions. The green diamonds and blue circles stand for the superconducting transition temperature determined from the resistance T_C(R-1) and ac susceptibility T_C(ac) measurements, respectively. The position of the red star denotes the location of the bi-critical point, which is determined by an intersection of extrapolated lines of the pressure-dependent T_M and T_C. The gray circles are the data extracted from the heat capacity results. The radial red line shows the suppressed tendency of T_C by the magnetic field. Reproduced with permission from Ref. [37].
