Abstract

It is shown experimentally that the La-Ba-Cu-O system has a new high-T//c phase La//2Ba//4Cu//6O//1//4// plus //y with oxygen-defect perovskite structure, other than the well-known La//2// minus //xBa//xCuO//4 with K//2NiF//4 structure. The new phase shows a superconducting transition at much higher temperatures (T//c onset greater than 55 K, T//c endpoint greater than 42 K) as compared with the K//2NiF//4 type phase.
