Abstract

During the investigation of the system Bi−Sr−Cu−O a novel family of superconducting oxides, close to the composition Sr2Bi2Cu2O7+δ has been isolated, with a midpoint critical temperature ranging from 7 K to 22 K. The X-ray diffraction and high-resolution electron microscopy studies have shown its relationships with perovskite and demonstrated its bidimensional character. The possible relationships of this lamellar oxide with Aurivillius phases is discussed.
