Özet:

 

Superconducting state parameters (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 (EMC) model  potential for the first time.  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 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.
