Spin and Orbital Order in Itinerant Ferromagnets

The long-standing problem of the effect of correlations on the ferromagnetism of transition metals is apparently nearing solution. The ferromagnetism of transition metal compounds, for instance doped manganites, poses a new question: is there some kind of orbital order coexisting with itinerant ferromagnetism? The ideas and techniques introduced by Gutzwiller should be of use again.

Two-stage orbital order and dynamical spin frustration in

The orbital degree of freedom is integral to many exotic phenomena in condensed matter, including colossal magnetoresistance and unconventional superconductivity. The standard model of orbital physics is the Kugel–Khomskii model1, which first explained the symmetry of orbital and magnetic order in KCuF3 and has since been applied to virtually all orbitally active materials2. Here we present Ram...

Orbital order and spin–orbit coupling in BaVS3

The correlated 3d sulphide BaVS3 undergoes a sequence of three symmetry breaking transitions which are reflected in the temperature dependence of the magnetic susceptibility, and its anisotropy. We introduce a microscopic model based on the coexistence of wide band a1g and localized eg d-electrons, and give the classification of the order parameters under the double space group and time reversa...

Spin model of magnetostrictions in multiferroic Mn perovskites.

We theoretically study origins of the ferroelectricity in the multiferroic phases of the rare-earth (R) Mn perovskites, RMnO(3), by constructing a realistic spin model including the spin-phonon coupling, which reproduces the entire experimental phase diagram in the plane of temperature and Mn-O-Mn bond angle for the first time. Surprisingly we reveal a significant contribution of the symmetric ...
