Entropy Driven Dimerization in a One-Dimensional Spin-Orbital Model

J. Sirker, G. Khaliullin

We study a new version of the one-dimensional spin-orbital model with spins S=1 relevant to cubic vanadates. At small Hund's coupling J_H we discover dimerization in a pure electro…

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…
