Superconducting properties of metallic glass Ca70Mg30 through Ashcroft's pseudopotential

The screened form factors obtained from the Ashcroft's empty core model pse udopotential for electron-ion interaction by employing Geldart and Vosko sc reening have been used for the prediction of the superconducting state prop erties viz. electron-phonon coupling strength lambda, Coulomb pseudopotenti al mu*, transition temperature T-c, isotope effect exponent alpha, and the interaction strength N0V of binary metallic glass Ca70Mg30. The results obt ained are in the expected range. The obtained T-c value of 17 K suggests su itability of this metallic glass for its use as lossless transmission line for cryogenic applications.
