Observation of a fluctuational tunneling conductivity of Cooper pairs in granulated superconductors
Svistunov V. M., Revenko Yu. F.
"Zero-bias anomalies" have been detected in the differential resistance of granulated composites. These anomalies are caused by a fluctuational tunneling conductivity of Cooper pairs. The dependence of this component of the conductivity has been studied as a function of the temperature, a magnetic field, and an electromagnetic field.
