T dependence of \(1/T_1T\) of \(^{77}\)Se measured at 6.02 T and color plot of \(1/T_1T\). (a) The data at ambient pressure, 1.0, 2.0, and 3.0 GPa were published in an eraly work20. \(T_{\mathrm{C}}\)s shown by arrows are determined from AC susceptibility measurements at 6.02 T. Both nematic and superconducting (SC) orders are absent at 1.0 GPa. (b) The SC phase shows a double-dome structure at 6.02 T. \(T_{\mathrm{C}}\)s shown by circles and inverted triangles are determined from AC susceptibility measurements at 0 T and 6.02 T, respectively. \(T_{\mathrm{C}}\)s shown by inverted triangles are the same as those shown by arrows in (a).
