Abstract

We have grown calcium and oxygen co-doped Y1-xCaxBa2Cu3O7-{\delta} single crystals using self-flux method. A method of fine tuning oxygen content to reach the equilibrium state through in situ monitoring of the conductivity change is established. Structural, compositional and electronic property characterizations of optimally co-doped Y1-xCaxBa2Cu3O7-{\delta} crystals indicate that they are high quality equilibrium crystals with a sharp superconducting transition width of 0.2K.
