Abstract
So far, magnetic polarons in antiferromagnetic semiconductors (ferrons) were assumed to arise due to the charge carrier self-trapping by a ferromagnetic or canted antiferromagnetic region. If the ferron size is not very large, they should have much more complicated structure: the magnetically deformed region consists not only of a magnetized core, which traps the electron, but also of its surrounding with the oppositely directed total moment, which repulses the trapped electron. The compensating moment of the surrounding oscillates with a period of the doubled lattice constant and with the amplitude diminishing very smoothly on an increase in the distance from the core.
