- Abstract
- Proximity-effect and resistance magneto-fluctuation measurements in submicron Nd(1.2)Ba(1.8)Cu(3)Oz (NBCO) nano-loops are reported to investigate coherent charge transport in the non-superconducting state. We find an unexpected inhibition of Cooper pair transport, and a destruction of the induced superconductivity, by lowering the temperature from 6K to 250 mK. This effect is accompanied by a significant change in the conductance-voltage characteristics and the zero bias conductance response to the magnetic field, pointing to the activation of a strong pair-breaking mechanism at lower temperature. The data are discussed in the framework of mesoscopic effects specific to superconducting nanostructures, proximity effect and high temperature superconductivity. (literal)
