Abstract
Interaction of two magnetic polarons formed either by single carriers or by excitons is considered in bulk crystal, quantum well and quantum wire. It is shown that the magnetic bipolaron can be formed if the di stance between two polarons is less than some critical value. This cri tical radius is the larger the lower the dimensionality of the system, the lower the temperature and the larger the single-polaron radius. T he critical distance for the neutral-magnetic-bipolaron formation is m uch longer than for the charged bipolaron.
