The evolution with temperature of magnetic polaron state in an antiferromagnetic chain with impurities
A. O. Sboychakov, A. L. Rakhmanov, K. I. Kugel +3
The thermal behavior of a one-dimensional antiferromagnetic chain doped by donor impurities was analyzed. The ground state of such a chain corresponds to the formation of a set of…
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…
On the absence of conduction electrons in the antiferromagnetic part of the phase-separated states in magnetic semiconductors
I. Gonzalez, J. Castro, D. Baldomir
We have calculated the energies of the phase-separated states for degenerate antiferromagnetic semiconductors including the possibility of the existence of conduction electrons in…
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…
The Ngai model of relaxation: An alternative for the study of an interacting system of small particles
J. Castro
It is shown that the Ngai model of relaxation accounts for the main experimental results of the magnetic relaxation in an assembly of interacting fine particles.
