Fig. 6: Electronic, magnetic, and SC phase diagram of PLCCO.

TN, Tf, and T* indicate Neel, partial spin-freezing, and fluctuating short-range antiferromagnetic (SR-AF) phase transition temperatures, respectively. LR-AF represents the long-range antiferromagnetic order phase. The schematic plot of SC and Zhole dome is based on the data shown in Fig. 3. The sign change in the Hall coefficient (RH) at low-T with overdoping is shown in Supplementary Fig. 10. Error bars are attributed to the ambiguity in determining the transition temperatures from λi(T) (i = 1, 2) (see Fig. 5 and Supplementary Fig. 9).
