BULK NEW HIGH-TC SUPERCONDUCTORS IN THE (PB,CU)SR2(CA,Y)CU2O7-DELTA AND (IN,PB,CU)SR2(CA,Y)CU2O7-DELTA SYSTEMS
Bulk superconductivity was observed in the systems (Pb0.75 Cu0.25)Sr2(Ca1-xYx)Cu2O7 -δ and (InyPb0.75-yCu0.25)Sr2 (Ca0.5Y0.5)Cu2 O7-δ. With decreasing x in (Pb0.75Cu0.25)Sr2 (Ca1-xYx)Cu2O7-δ, Tc increases up to 55 K at x = 0.1; however this specimen is multiphasic with superconducting Meissner volum...
