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…

Optical evidence of quantum rotor orbital excitations in orthorhombic manganites
N. N. Kovaleva, K. I. Kugel, Z. Potucek +8
In magnetic compounds with Jahn-Teller (JT) ions (such as Mn3+ or Cu2+), the ordering of the electron or hole orbitals is associated with cooperative lattice distortions. There the…
