Magnetic superlattices and multilayers

We briefly review the active areas of current research in magnetic superlat tices, emphasizing later years. With recent widening use of advanced techno logies, more emphasis has been made on quantitative atomic level chemical a nd structural characterization. Examples where the multilayer structure has been controlled, characterized and correlated with the physical properties are discussed. The physical properties are categorized according to the co mplexity of a structure needed to observe a particular effect. We outline a number of general important unsolved problems, which could considerably be nefit from theoretical and experimental input. An extensive list of magneti c multilayer materials is provided, with references to recent publications. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
