Investigations of vanadium oxide bronzes θ-(Fe 1- yAl y) xV 2O 5
Abstract
The vanadium oxide bronzes θ-(Fe 1- yAl y) xV 2O 5 are Curie-Weiss paramagnets and hopping semiconductors. The samples studied were synthesized by direct solid-state reaction and investigated by the X-ray diffraction, differential thermal analysis, electrical resistivity, magnetic susceptibility, and Mössbauer techniques. The crystal lattice parameters, effective magnetic moments of Fe 3+ cations, Curie-Weiss temperatures, and the values of 57Fe hyperfine interaction parameters were determined. Endothermic effects were observed for some of the samples.
