Superconducting state parameters of metallic glass Mg70Zn30 using different dielectric screenings

Using Ashcroft's empty core model potential, the superconducting state parameters viz. electron-phonon coupling strength (λ), Coulomb pseudopotential (μ*), isotope effect exponent (α), the interaction strength and the transition temperature (Tc) are calculated for six dielectric screenings for the first time. The results show variation in interaction in electrons and phonons. The value of the Tc changes within the expected range with experimental data. The results are being reported in this research articles. (orig.)
