The Critical Temperature of an Anisotropic Superconductor in the Presence of a Homogeneous Magnetic Field and Impurities

TL;DR

This paper investigates how a homogeneous magnetic field and nonmagnetic impurities affect the critical temperature of anisotropic superconductors, clarifying the role of pair-breakers in relation to order parameter anisotropy.

Contribution

It provides a theoretical analysis of the combined effects of magnetic fields and impurities on the critical temperature in anisotropic superconductors.

Findings

Magnetic fields and impurities lower the critical temperature.

The impact depends on the anisotropy of the order parameter.

Pair-breakers influence the superconducting transition in specific ways.

Abstract

The effect of a homogeneous magnetic field and nonmagnetic impurities on the critical temperature of an anisotropic superconductor has been investigated. The role of these pair-breakers in relation to the anisotropy of the order parameter is clarified.
