Metallic Magnetic Superlattices

Abstract

Artificially made, ordered material systems are a pillar of late‐20th‐century advanced technology. In principle, metallic magnetic superlattices—also called magnetic multilayers—should exhibit more new and interesting physical effects than any other artificially made material system. This gives them the potential for many technological advances in information storage and retrieval and in the synthesis of new magnets for a variety of applications. Structures made by the orderly deposition of alternating thin films of two or more metals, at least one of which is magnetic, exhibit new physical effects and have great technological potential.
