Abstract

The theoretical study of the superconducting state parameters (SSP) namely electron–phonon coupling strength λ, Coulomb pseudopotential μ ∗, transition temperature T C , isotope effect exponent α, and effective interaction strength N O V of 4d-transition metals superconductors have been made extensively in the present work using a model potential formalism for the first time. In the present computation, the use of pseudo-alloy-atom model (PAA) is proposed and found successful. A considerable influence of various exchange and correlation functions on λ and μ ∗ is found from the present study. The present results of the SSP are found in qualitative agreement with the available experimental data wherever exist.
