| dc.description.abstractEn | The fluctuating superconducting correlations emerging in dirty hybrid structures under the conditions of the strong proximity effect are demonstrated to affect the validity range of the widely used formalism of Usadel equations at mesoscopic scales. In superconductor ferromagnet structures these giant mesoscopic fluctuations originating from the interference effects for the Cooper pair wave function in the presence of the exchange field can be responsible for an anomalously slow decay of superconducting correlations in a ferromagnet even when the noncollinear and spin orbit effects are negligible. The resulting sample to sample fluctuations of the Josephson current in superconductor ferromagnetic superconductor junctions and the local density of states in superconductor ferromagnetic hybrid structures can provide an explanation of the long range proximity phenomena observed in mesoscopic samples with collinear magnetization. | |
