The magnetic order in the tetragonal M2CuO2CI2, M=Ca, Sr and in Sr2CuO3+ x compounds was studied by using Mossbauer spectroscopy of 0.5% ~ IFe-doped samples. These compounds crystallize in a K2NiF 4 -type tetragonal structure, isestructural to La2.xSrxCuO 4 superconductors. In this structure, one cr

The structure of the compound \(\mathrm{Sr}_{2} \mathrm{CuO}_{2}\left(\mathrm{CO}_{3}\right)\) has been reexamined by means of electron diffraction and high resolution electron microscopy. It was found that next to the body centered structure, a second variant of the structure, based on a primitive
We have succeeded in synthesizing the insulating phase of Bi 2 Sr 2 CuO 6ุ (Bi2201) with the stoichiometric cation composition by use of a heat treatment technique in an evacuated tube with titanium powders. The excess oxygen content and the average valence of Bi were determined electrochemically by
