Spin-dependent transport in phase-separated manganites
K. I. Kugel, A. L. Rakhmanov, A. O. Sboychakov +3
Starting from the assumption that ferromagnetically correlated regions exist in manganites even in the absence of long-range magnetic order, we construct a model of charge transfer…
Magnetic polarons in doped 1D antiferromagnetic chain
I. González, J. Castro, D. Baldomir +3
The structure of magnetic polarons (ferrons) is studied for an 1D antiferromagnetic chain doped by non-magnetic donor impurities. The conduction electrons are assumed to be bound b…
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…
