Probing Structural Anomalies in LaCoO3 using Neutron Total Scattering

Abstract: This proposal is concerned with investigating changes in the local structure of LaCoO3 at various temperatures. The arrangement of d-electrons in the transition metal, Co, changes as a function of temperature, going from the so-called 'low-spin' state (which tends to be quite rare in oxide materials) at low temperature to a 'high-spin' state at higher temperatures. These changes must have an effect on the local environment surrounding the Co atoms, i.e. the atomic structure, but any such distortions are not readily seen in the average crystal structure, as determined from standard diffraction experiments. This experiment will use total scattering to probe the local, short-range atomic structure of the material, and provide insight into how the changes in electronic structure manifest.
