Preparation and Properties of La (2-x) Bi(x) CuO4 (.1 > or = x > or = 0)

Abstract

Samples of La2-xBixCu04 were prepared by codecomposition of the nitrates in air. Single phase products were obtained for x < or = 0.10. The substitution of bismuth for lanthanum resulted in an increase in delocalization of holes, as indicated by increased conductivity and a decrease in the Neel temperature. Samples were also annealed in argon at 600 C and their properties compared with the samples as prepared in air. Keywords: Lanthanum compounds, Bismuth, Copper oxides, Solid state chemistry, Crystals, Antiferromagnetism, Crystal structure, Vacancies (Crystal defects), Anions, Phase transitions, Transition temperature, Magnetic anomalies, Perovskites.
