Study of superconducting state parameters of binary BeCAL100-C metallic glasses

The theoretical investigation of the superconducting state parameters (SSP) viz. electron-phonon coupling strength λ, Coulomb pseudopotential μ*, transition temperature TC, isotope effect exponent a and effective interaction strength NoV of BeCAl100-C (at C = 10 and 30 at %) 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 the aforesaid properties. It is observed that the electron-phonon coupling strength λ and the transition temperature TC are quite sensitive to the selection of the local field correction functions, whereas the Coulomb pseudopotential μ*, isotope effect exponent α and effective interaction strength NoV show weak dependences on the local field correction functions. The TC obtained from lU-local field correction function are found to be in an excellent agreement with available theoretical or experimental data. Also, the present results are found in qualitative agreement with other such data reported earlier, what confirms the superconducting phase in the metallic glasses.
