SUPERCONDUCTIVITY AND THE METAL-SEMICONDUCTOR TRANSITION IN THE SEPTENARY OXIDE SYSTEM, (TL0.5PB0.5)(CA1-YYY)SR2CU2O7-DELTA
The septenary compound (Tl0.5Pb0.5)(Ca1-yYy)Sr2Cu2O7-δ exhibits the highest superconducting transition temperature (110 K) yet observed in the TlCaBa2Cu2O7-δ (1122) structure type. This complex, six-blend combination of metallic elements which make up the material is, however, compensated by a relat...
