Relation between transition temperature and \(\gamma\) coefficient. a Superconducting transition temperature \(T_{\mathrm{c}}\) as a function of Al content. Note that \(T_{\mathrm{c}}\) shows the sharp drop at Al content of about 15% corresponding to the QC and the 2/1AC. b Electronicspecific heat coefficient \(\gamma\) as a function of Al content. The slight drop at 15% Al content suggests the pseudogap formation. c Correlation between \(T_{\mathrm{c}}\) and \(1/\gamma\). The straight line denotes the interrelationship, \(\ln T_{\mathrm{c}} \propto 1/\gamma\), marking the constant pairing interaction
