Anisotropy of Sommerfeld coefficient and penetration depth in superconducting 2H-NbS2

Abstract

We proposed anisotropic properties of Sommerfeld coefficient as well as penetration depth for superconducting 2H-NbS2 by using modified phenomenological GL-theory for multi band superconducting system. Calculated results are very close with the corresponding experimental findings reported earlier. Similarly, anisotropy of penetration depths obtained successfully following the same model of GL-theory. The analysis reveals that present proposed model can successfully be used for explaining anisotropy of transitional metal dichalcogenide compounds (TMDs).
