COMPOSITION-INDUCED SUPERCONDUCTIVITY (UP TO 55-K) IN THE SYSTEM (PB0.75CU0.25)SR2(CA1-XYX)CU2O7-DELTA
We demonstrate a compositionally induced superconductor-to-semiconductor transition in the system (Pb0.75Cu0.25)Sr2(Ca1-xYx)Cu2O7-δ. Superconducting behavior is observed over the composition range 0.1 ≤ x ≤ 0.6. Samples with 0.1 ≤ x ≤ 0.3 are multiphasic, but the superconducting transition temperatu...
