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