Superconducting State Parameters of Nb x Ta y Mo z Superconductors

Abstract: We present screening dependence theoretical investigations of the superconducting state parameters, i.e. electronphonon coupling strength πœ†, Coulomb pseudopotential πœ‡ * , transition temperature 𝑇𝐢 , isotope effect exponent 𝛼, and effective interaction strength 𝑁0𝑉 , of some BMG superconductors, namely Nb0.45Ta0.45Mo0.10, Nb0.30Ta0.40Mo0.30, Nb0.40Ta0.30Mo0.30, Nb0.30Ta0.30Mo0.40 and Nb0.15Ta0.15Mo0.70 by employing the well-known empty core model potential of Ashcroft for the first time. Five local fiel… Show more

“…The Ashcroft's empty core (EMC) model potential is a simple one-parameter model potential [15], which has been successfully found for various metallic complexes with various form of the screening functions [3][4][5][6][7][8][9][10][11][12]. Therefore, in the present work we use Ashcroft's empty core (EMC) model potential with more advanced Ichimaru-Utsumi (IU) [ [20] local field correction functions for the first time in the present case.…”

“…In the present work, r C is fitted with experimental T C of the ternary amorphous alloys for most of the local field correction functions. In the present investigation for (Ni 33 Zr 67 ) 1 βˆ’ x M x (x = 0, 0.05, 0.1, and 0.15, M = Cu) ternary amorphous superconductors, the electronphonon coupling strength Ξ» is computed using the relation [3][4][5][6][7][8][9][10][11][12] …”
