Low temperature mixed spin state of Co³⁺ in LaCoO₃ evidenced from Jahn–Teller lattice distortions

One- and multi-phonon excitations of the single crystalline LaCoO₃ were studied using Raman spectroscopy in the temperature region of 5–300 K. First-order Raman spectra show a larger number of phonon modes than allowed for the rhombohedral structure. Additional phonon modes are interpreted in ter...
