Abstract

The recent investigations of superconductivity in ternary or pseudo ternary copper oxides recently performed by numerous staffs all over the world, show that up to the present, only two structural families belonging to the La2CuO4 and YBa2Cu3O7 types, exhibit high critical temperatures, i.e. greater than 30K. The main factors which govern the superconducting properties are discussed here in a first point. YBa2Cu3O7–8, appears as most fascinating owing to its high Tc (92K), but also very complex owing to its large possible oxygen deviation from stoichiometry. Its structural evolution versus oxygen non stoichiometry involving extended defects is presented in connection with its superconducting properties. The substitution of copper by a magnetic element, iron, very recently performed is finally presented here, taking into account the oxygen stoichiometry in the oxides YBa2Cu3-XFeXO7.
