Reentrance and Magnetic-Field-Induced Superconductivity with Kondo Impurities: Bulk and Proximity Systems
arXiv:1204.5618 · doi:10.1103/PhysRevB.86.064509
Abstract
Reentrant behavior is known to exist and magnetic-field-induced superconductivity has been predicted in superconductors with Kondo impurities. We present a simple framework for understanding these phenomena and generalize it to explain the long-standing puzzle of paramagnetic reentrance in thick proximity systems as due to small amounts of Kondo impurities.
