QUANTUM-WELL STATES IN METALLIC SUPERLATTICES

Spin-polarized band structures of Fe-n/Cr-m superlattices have been co mputed 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 den sity of states display features which are identified as quantum well-l ike states. We discuss the role these confined states play in the inte rlayer coupling and transport properties of metallic superlattices.
