Pagination or Media Count:
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.
