Compensation of Magnetic Impurity Effect in Superconductors by Radiation Damage
Mi-Ae Park, M. H. Lee, Yong-Jihn Kim
Abstract
Compensation of the reduction of Tc caused by magnetic impurities has been observed as a consequence of radiation damage. Using the recent theory by Kim and Overhauser (KO) we consider the effect of radiation damage on the Tc of superconductors having magnetic impurities. We find a good fitting to the experimental data. It is also pointed out that Gor'kov's formalism with the pairing constraint derived from the Anomalous Green's function leads to KO theory.
