Spin-polarized band structures of ${\rm Fe}_n/{\rm Cr}_m$ superlattices have been computed for both ferromagnetic and antiferromagnetic configurations of the iron layers by using both the layered KKR and augmented spherical wave formalisms. Along the growth direction the band structure and density of states display features which are identified as quantum well-like states. We discuss the role these confined states play in the interlayer coupling and transport properties of metallic superlattices.
