Description

We have grown calcium and oxygen co-doped Y1-xCaxBa2Cu3O7-δ (CD-Y123) single crystals using a self-flux method. A process of fine tuning the oxygen content to reach the equilibrium state through in situ monitoring of the conductivity change is established. Structural, compositional and electronic property characterizations of optimal CD-Y123 crystals indicate that they are high quality equilibrium crystals with a sharp superconducting transition width of 0.2 K.
