Abstract
Temperature dependence of the structural parameters is investigated in LaCoO 3 that shows a spin state transition at T spin ∼100 K by means of high-resolution time-of-fight (TOF) neutron powder diffraction measurements. We have found that the structural parameters, such as, Co–O bond length d and Co–O–Co bondangle Θ, show no detectable anomaly at T spin . We have compared these structural features of LaCoO 3 with those of the so-called spin-crossover complexes.Keywords
