Article abstract of DOI:10.1016/S0925-8388(99)00214-5

Single crystals of a new bismuth indium niobate, Bi₅In₂Nb₃O_18-x, were grown by subsolidus reaction method. Differential thermal analysis measurements indicate that the compound has a melting point of 1224 °C. Single crystal and powder X-ray diffraction methods show that the compound has the tetragonal system; P4/mbm space group, and lattice constants are a = 12.6548(5), and c = 3.9231(3) angstroms. The magnetic susceptibilities of compound Bi₅In₂Nb₃O_18-x indicate Curie-Weiss behavior with an effective magnetic moment μ_eff = 0.72(1) μ_B.
