Resonant proximity effect in normal metal/diffusive ferromagnet/superconductor junctions
Resonant proximity effect in the normal metal/insulator/diffusive ferromagnet/insulator/swave and d-wave superconductor N/I/DF/I/S junctions is studied for various regimes by solving the Usadel equation with the generalized boundary conditions. Conductance of the junction and the density of states in the DF layer are calculated as a function of the insulating barrier heights at the interfaces, ...

متن کاملSize effects in the density of states in normal-metal-superconductor and superconductor-normal-metal-superconductor junctions.
The quasiparticle local density of states ~LDOS! is studied in clean normal-metal–superconductor ~NS! and superconductor–normal-metal–superconductor ~SNS! junctions with increasing transverse size, from quasione-dimensional to three-dimensional. It is shown that finite transverse dimensions are related to pronounced effects in the LDOS, such as fast oscillations superimposed on the quasiparticl...
متن کاملShot Noise and Proximity Effect in Superconductor–normal-metal Heterostructures
Current noise provides useful information on correlations important for transport properties of mesoscopic systems. Of particular interest, both experimentally and theoretically, are heterostructures of normal metals and superconductors. We use an extended Keldysh-Green’s function approach to calculate the current correlations fully accounting for the superconducting proximity effect. The shot ...
متن کاملAnomalous proximity effect in mesoscopic normal-metal–superconductor structures
Anomalous corrections to the resistance have been found in mesoscopic normal-metal–superconductor ~NS! structures below TC . They differ from those described by the classical ‘‘proximity’’ theory in sensitivity to magnetic field, temperature, and rf irradiation. Contrary to the case of the classical proximity effect the anomalous corrections can be both positive and negative. A possible model w...
