- Abstract
- We present measurements of the transport properties of hybrid loops consisting of a Kondo AuFe film and a superconducting Al film. The temperature dependence of the resistance and the significant phase modulation of the resistance indicate the existence of the superconducting proximity effect over the range of similar to 0.5 mu m in AuFe wires with Fe concentrations of 26 ppm and 70 ppm. The magnetoresistance oscillation of AuFe/Al hybrid loops shows a reentrant behavior in temperature. The electronic phase coherence in the Kondo AuFe wires has been further confirmed by the weak localization measurement.
