Abstract

Electron dephasing in disordered metals with superconductive grains were analyzed. It was shown that electron-electron interaction was considered nonperturbatively and was responsible for strong deviation of the dephasing rate from the standard predictions. It was found that in the three-dimensional case the MT correction could be large or small compared to the WL correction, depending on temperature and other parameters of the problem. It was demonstrated that a small concentration of superconductive islands can enhance considerably the low-temperature dephasing rate in disordered metals as observed through the low-field magnetoresistance.
