摘要：

Temperature dependence of the structural parameters is investigated in LaCoO3 that shows transition at T-spin similar to 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 theta, show no detectable anomaly at T-spin. We have compared these structural features of LaCoO3 with those of the so-called spin-crossover complexes.
