【 摘 要 】

Our well-recognized pseudopotential is used to investigate the superconducting state parameters viz; electron–phonon coupling strength 𝜆, Coulomb pseudopotentialµ 𝜇*, transition temperature 𝑇c, isotope effective exponent 𝛼 and interaction strength 𝑁0𝑉 for the In1-𝑥Zn𝑥 and In1-𝑥Sn𝑥 binary alloys. We have incorporated six different types of local field correction functions, proposed by Hartree, Taylor, Vashistha–Singwi, Ichimaru–Utsumi, Farid et al and Sarkar et al to show the effect of exchange and correlation on the aforesaid properties. Very strong influence of the various exchange and correlation functions is concluded from the present study. The comparison with other such theoretical values is encouraging, which confirms the applicability of our model potential in explaining the superconducting state parameters of binary mixture.
