Abstract :Superconducting state parameters insert ignore into journalissuearticles values(SSP); viz. electron-phonon coupling strength l, Coulomb pseudopotential m*, transition temperature TC, isotope effect exponent a and effective interaction strength NO V of seven Cu1-c Snc binary metallic glasses have been reported using Ashcroft`s empty core insert ignore into journalissuearticles values(EMC); model potential for the first time. Five local field correction functions proposed by Hartree insert ignore into journalissuearticles values(H);, Taylor insert ignore into journalissuearticles values(T);, Ichimaru-Utsumi insert ignore into journalissuearticles values(IU);, Farid et al. insert ignore into journalissuearticles values(F); and Sarkar et al. insert ignore into journalissuearticles values(S); are used in the present investigation to study the screening influence on the aforesaid properties. The TC obtained from H-local field correction function are found in qualitative agreement with available experimental data and show linear nature with the concentration c of element Sn. A linear TC equation is proposed by fitting the present outcomes for H-local field correction function, which is in conformity with other results for the experimental data. Also, the present results are found in qualitative agreement with other such earlier reported data, which confirms the superconducting phase in the metallic glasses.
