Onset of ATC superconductivity in Ag5Pb2O6/CuO composite

Abstract

Meissner type superconductivity extending up to 13 - 18 degrees Celsius was confirmed in the composite material consisting of metallic particles Ag5Pb2O6 dispersed in an insulating CuO matrix, and superconductivity mechanism is based upon inter particle interaction acting in the quantum tunnelling regime.
