Fingerprints of the Jahn-Teller and superexchange physics in optical spectra of manganites
N. N. Kovaleva, O. E. Kusmartseva, K. I. Kugel
Transition metal oxides incorporating Jahn-Teller (JT) ions Mn3+ (3d4) in manganites and Cu2+ (3d9) in cuprates exhibit outstanding magnetic and electronic properties, including co…

Fingerprints of Mott-Hubbard physics in optical spectra of antiferromagnetic LaTiO3
N. N. Kovaleva
Magnetic properties of Mott-Hubbard insulators are determined by superexchange interactions mediated by the high-spin (HS) and low-spin (LS) intersite d-d charge excitations, which…
