Resistance anomaly near the superconducting transition temperature in short aluminum wires

A systematic experimental study is reported of the superconducting resistive transition in one-dimensional Al wires of length 0.6-110 mu m. Shorter wires show a peak in resistance as a function of temperature near T sub c , with a value above the normal-state resistance. Near the peak, the resistanc...

Description
Summary:A systematic experimental study is reported of the superconducting resistive transition in one-dimensional Al wires of length 0.6-110 mu m. Shorter wires show a peak in resistance as a function of temperature near T sub c , with a value above the normal-state resistance. Near the peak, the resistance decreases sharply in a magnetic field only a few Oe. In the same regime, the current--voltage characteristic resembles that of a superconductor-insulator-normal tunnel junction. These new results may be a manifestation of coherent effects in small superconducting samples.
