Screening dependence investigations of the superconducting stateparameters (SSP), namely the electron–phonon coupling strengthλ, Coulomb pseudopotentialμ*, transition temperatureTC, isotope effectexponent α and effectiveinteraction strength NOV of ten binary CuCZr100−C (C = 0.25,0.30,0.33,0.35,0.40,0.45,0.50,0.55,0.57 and 0.60) metallic glasses have been reported using Ashcroft’s empty core (EMC)model potential. Five local field correction functions proposed by Hartree(H), Taylor (T), Ichimaru–Utsumi (IU), Farid et al (F) and Sarkar et al (S)are used in the present investigation to study the screening influence on theaforesaid properties. It is observed that the electron–phonon coupling strengthλ and the transitiontemperature TC are quite sensitive to the selection of the local field correction functions, whereas the Coulomb pseudopotentialμ*, isotope effectexponent α and effectiveinteraction strength NOV show weak dependences on the local field correction functions. TheTC obtained from the H-local field correction function is found to be in qualitative agreement withavailable theoretical or experimental data and shows an almost linear nature with the concentrationC of the elementCu. A linear TC equation is proposed by fitting the present outcomes for the H-local field correctionfunction, which is in conformity with other results for the experimental data.Also, the present results are found to be in qualitative agreement with other suchdata earlier reported, which confirms the superconducting phase in the metallicglasses.
