Unconventional behavior of superconducting nanostructures

2000

Abstract Various aluminium nanostructures have been studied experimentally. Unusual nonmonotonous dependence of the critical current on external magnetic field has been observed. Pronounced nonlocal interaction has been found to decay exponentially on a scale of the superconducting coherence length ξ(T).

Nonlocality in superconducting microstructures

2001

We discuss experimental evidence of nonlocality in electron transport of small structures. It is shown that for superconductors reasonable agreement with experiment can be achieved by assuming exponential decay of the nonlocal interaction ∝ exp(—Lξ), where L is the distance between the interacting points and ξ is the correlation length. ξ is associated with the Ginzburg - Landau coherence length ξGL.
