Site preference of the partially substituted 3d metal M and superconducting and magnetic properties have been investigated for Pb2Sr2Y1 − xCax(Cu1 − yMy)3O8 (M = Fe, Co, Ni, Zn, Ga). It has been found from powder neutron diffraction that Fe atoms

The compound Pb2Sr2ACu3O8+δ (A: lanthanide Ln or Y) is characterized by double CuO2 pyramidal layers and an almost oxygen-free CuOδ layer, where the valences of Cu are about +2 and +1, respectively. The CuOδ layer can accomodate extra oxygen up to

The Hall effect of ceramic samples of Pb 2 Sr 2 Y 1−x Ca x Cu 3 O 8 has been investigated for 0 ≦ x ≦ 0.5. The Hall coefficient R H is positive and decreases with increasing x, which is explained within the doped Mott-Hubbard model. For x H inc
