Superconductivity and phase separation of La2CuO4+delta single crystals

Abstract:

Lanthanum cuprate( La2CuO4) is an antiferromagnetic insulator, which becomes superconducting after introducing interstitial oxygen by high-pressure, chemical or electrochemical oxidation We report here the flux growth of superconducting single crystal in an ambient atmosphere, which the morphology is remarkably different from that of insulating crystal. The behavior of superconductivity is studied by AC-susceptibility measurement. A phase separation makes a strong effect on the superconductiv...
