The crystal structure undergoes a change of symmetry depending on the size of the RE cation. LaCoO3 is rhombohedral, S.G. R3̅c (No. 167), while, for the rest of the RE series (Pr–Dy), the symmetry is orthorhombic, S.G. Pnma (No. 62). The crystal structure obtained by X-ray diffraction was confirmed by high-resolution transmission electron microscopy, which yielded a good match between experimental and simulated images. It is further shown that the well-known magnetism in LaCoO3, which involves a thermally induced Co3+ (d6) low spin to intermediate or high spin state transition, is strongly modified by the RE cation, and a rich variety of magnetic order has been detected across the series.engjournal article1520-510Xhttps://doi.org/10.1021/acs.inorgchem.6b02557open accessCobaltitesPerovskiteMicrowave synthesisMagnetismQuímica inorgánica (Química)2210.28 Química del Estado Sólido2303 Química Inorgánica
