LaCoO3 has a thermally induced spin state transition from an S=0 (<90K) to an excited state. In the low spin state localized holes (electrons) bound to cobalt ions or oxygen interstitial (vacancies) sites induce low spin to high spin transitions in neighbouring Co$^{3+}$ ions, leaving the remaining cobalt ions in the low spin ground state. The radius of the anisotropic magnetic polaron/exciton will extend over several unit cells, creating large spin clusters which are dilute within the solid, the concentration of which is related to the oxygen vacancy concentration. A SANS neutron scattering experiment has already been performed and suggests a direct observation of the polarons for the first time. We would like to extend the initial investigation to lower temperatures to see how the interactions are modified and to see how the intensity is changed by varying field and oxygen content.
