Specific heat data for y = 0.4. (a) Specific heat (C/T) data under magnetic fields (B) of 0 and 5 T plotted as a function of T2. By fitting the data under B = 5 T, electronic specific heat parameter (γ) and Debye temperature (θD) were estimated. (b) Temperature dependence of the electronic contribution (Cel/T) under B = 0 T. The electronic contribution was calculated by subtracting the lattice contribution. Tc and the superconducting jump at Tc (ΔC) were estimated by considering the entropy balance, as guided by the red dashed lines. ΔC/γTc = 1.34, which is close to BCS value of 1.43.
