A series of solid solutions containing CO3 groups, (CyCul\_y)(Srl \_z/2Caz/2)2(Y1 \_xCax\_zSrz)Cu20 d with 0.30<x <0.70, was prepared at 1313 K under the atmosphere of 02-4202. The values ofy (0.48-0.67) and z (0.14--0.28) depend on the total Ca content, x. The length of the a-axis increases from 3.
We report the preparation of almost phase pure (T10.sPbo.s)Sr2Ca2Cu3Og, which is characterized by high temperature superconductivity with TΒ’onset= 130 K, Tcmidpoint= 124 K, Tczero= 122.5 K as measured by electrical resistance, and a diamagnetic onset temperature, Tcm~ of 124 K determined by DC magne
