Structural anomalies, spin transitions and charge disproportionation in LnCoO3

K. Knizek, Z. Jirak, J. Hejtmanek +2

The diamagnetic-paramagnetic and insulator-metal transitions in LnCoO3 perovskites (Ln = La, Y, rare earths) are reinterpreted and modeled as a two-level excitation process. In dis…
