METAL-SUPERCONDUCTOR-INSULATOR TRANSITION IN THE (TL1-XPBX)(CAL-YYY)SR2CU2O7-DELTA SYSTEM
The (Tl1-xPbx) (Ca1-yYy) Sr2Cu2O7-δ system exhibits the highest superconducting transition temperature (110K), at x=0.5 and y=0.2, 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...
