Insulator-Metal Transition and Superconductivity in CuCi
Abstract
Our results obtained under AFOSR support provided an unambigous experimental evidence for the CuCl oxidation at ambient conditions resulting in the formation of antiferromagnetic clinoatacamite Cu2Cl(OH)3 and CuO phases, intimately related to the measured localized superconductivity. Superconducting effects observed for T < TN2 = 6.5 K in the case of Cu2Cl(OH)3 and in the temperature interval TN2 < T < 340 K in the case of CuO coincide with fluctuating short-ranged ordered magnetization measured in these materials, resembling the behavior of RVB quantum spin liquid proposed for cup rates. Thus, our results strengthen the Andersons conjecture on superconductivity in CuCl and may have far-reaching consequences.
