Abstract
Heterostructures composed of magnetic and nonmagnetic semiconductor layers are investigated within the framework of the tight-binding model. The band structure and local densities of states (DOS) are calculated. Spin-dependen t modifications are found in DOS of nonmagnetic layers for thin spacers. A coupling between magnetic moments across a nonmagnetic spacer is discussed.
