Theory of a large thermoeffect in superconductors doped with magnetic impurities
arXiv:1203.2459 · doi:10.1103/PhysRevLett.109.147004
Abstract
We argue that parametrically strong enhancement of a thermoelectric current can be observed in conventional superconductors doped by magnetic impurities. This effect is caused by violation of the symmetry between electron-like and hole-like excitations due to formation of subgap Andreev bound states in the vicinity of magnetic impurities. We develop a quantitative theory of this effect and demonstrate that it can be detected in modern experiments.
