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…

Stabilization of magnetic polarons in antiferromagnetic semiconductors by extended spin distortions
J. Castro, I. Gonzalez, D. Baldomir
We study the problem of a magnetic polaron in an antiferromagnetic semiconductor (ferron). We obtain an analytical solution for the distortion produced in the magnetic structure of…

Phase diagram as a function of temperature and magnetic field for magnetic semiconductors
I. Gonzalez, J. Castro, D. Baldomir
Using an extension of the Nagaev model of phase separation (E.L. Nagaev, and A.I. Podel'shchikov, Sov. Phys. JETP, 71 (1990) 1108), we calculate the phase diagram for degenerate an…
