Abstract

Effects of europium substitution on the stoichiometry, structure and superconductivity of the Bi₂Sr₂CaCu₂O _8+y phase have been investigated. Partial replacement by calcium by europium promotes the single-phase formation and leads to an uptake of extra oxygen into the structure. Oxygen content in the Bi₂Sr ₂Ca_1-xEu_xCu₂O_8+y materials was determined by the thermogravimetric hydrogen reduction method. In an attempt to locate the intercalated oxygen atoms, X-ray, neutron and electron diffraction techniques were used. In addition, the samples were characterized by AC magnetic susceptibility measurements as well as by ¹⁵¹Eu Mossbauer spectroscopy. The applicability of these methods and the results obtained thereby are discussed.
