Abstract

Abstract Neutron diffraction, dta and electrical conductivity measurements do not reveal the previously reported first-order localised to itinerant electron phase transition of LaCoO 3 near 121OK. Instead, a broad higher-order semiconductor to metal transition is observed between approximately 520K and 750K. These new data simplify possible interpretations of the electronic behaviour of LaCoO 3.
