On the Triplet Superconductivity in Nearly Ferromagnetic Dirty Metallic Films —The Effect of Weak Localization

Abstract

Possible effects on recovery of the transition temperature T_c of the triplet superconductivity is argued for dirty nearly ferromagnetic metallic films. As a consequence of the weak localization, higher order corrections of the repulsive interaction leads to the remarkable reduction of pair-breaking parameter for a small energy Cooper pairs at low temperatures. The transition temperature is determined by Cooper pairs of wider energy range and its recovery is of order −λ ln (1−\barI), where λ and \barI are parameters of the localization and the interaction, respectively.
