Charge order versus Zener polarons: ferroelectricity in manganites
Dmitry V. Efremov, Jeroen van den Brink, Daniel I. Khomskii
We show that in manganites close to half-doping novel non-bipartite magnetic phases appear due to the interplay between double exchange, superexchange and orbital ordering. In cons…
Orbital Dimerization and Dynamic Jahn-Teller Effect in NaTiSiO
M. J. Konstantinović, J. van den Brink, Z. V. Popović +3
We study with the Raman scattering technique two types of phase transitions in the pyroxene compounds NaMSiO (with M=Ti, V, and Cr). In the quasi one-dimensional S=1/2 syst…
Orbital effects in manganites
Jeroen van den Brink, Giniyat Khaliullin, Daniel Khomskii
We review some aspects related to orbital degrees of freedom in manganites. The Mn ions in these compounds have double orbital degeneracy and are strong Jahn-Teller ions, ca…
Coulomb interaction and stability of CE-type structure in half-doped manganites, reply
Jeroen van den Brink, Giniyat Khaliullin, Daniel Khomskii
In his Comment (cond-mat/0104353), Shen points out that the on-site Coulomb interaction, that can cause charge order in half-doped manganites, also destabilizes the magnetic CE-pha…
Spin and orbital excitations in magnetic insulators with Jahn-Teller ions
J. van den Brink, W. Stekelenburg, D. I. Khomskii +2
The elementary excitations of a model Hamiltonian that captures the low energy behavior of a simple two-fold degenerate Hubbard Hamiltonian with Hund's rule coupling, is studied. T…
