Temperature-doping phase diagram of Na1−xLi x FeAs. TSDW, Tnem, \(T_{\mathrm{c}}^\rho\), and \(T_{\mathrm{c}}^\chi\) were obtained by our transport, magnetization, and NMR measurements which turn out to be consistent one another. The emerging phase at T0 before entering the bulk SC state is seemingly connected to the nematic transition at lower dopings. The shade of green below Tc schematically represents the SC volume fraction obtained from Fig. 1c
