N1 - Funding Information: Freeman A.J. Arthur J. Freeman is Morrison Professor of physics at Northwestern University, having joined the faculty of Northwestern in 1967 as chairman of the Physics Department. A member of the Materials Research Society and several professional and governmental committees, Freeman has published more than 400 papers, and is editor of the Journal of Magnetism and Magnetic Materials . He received BS and PhD degrees from the Massachusetts Institute of Technology, and has received numerous honors including Guggenheim and Fulbright Fellowships and the Alexander von Humboldt Senior Fellowship. Continenza A. Alessandra Continenza recently received her PhD in physics at Northwestern University, where she has been working on theoretical calculations of the properties of several semiconducting Systems and interfaces. Currently she is a postdoctoral researcher at Northwestern, but will soon be returning to her native Italy as assistant research professor in the Physics Department at the Universitá di L'Aquilla. Li Chun Chun Li is a postdoctoral researcher in the Magnetic Theory Group at Northwestern University, where he recently received his PhD. He received his undergraduate education from the University of Science and Technology of China, where his emphasis was on low temperature physics. Li's recent research work has focused on computational studies of electronic and magnetic properties of solid state surfaces, interfaces, and thin films. 09 1990 15 9 27 33 Copyright © Materials Research Society 1990 1990 Materials Research Society The importance of interfaces in determining the physical properties of technologically important materials — addressed in the Guest Editors' introduction to the articles in this issue — has stimulated theoretical efforts to determine from first principles a detailed understanding of their chemical, electronic, and mechanical properties. Fortunately, this has now been made possible as a result of the dramatic advances in condensed matter theory made in the last decade, driven in large part by new and sophisticated experiments on high-purity materials that have been well and carefully characterized. Particularly in electronic structure, these advances may be attributable directly to the close collaboration of theoretical and experimental researchers. Indeed, the new found ability to apply fundamental theoretical concepts to real materials (rather than to simple model systems) made possible by using the continued rapid development of computer power, has served to fill the increasingly urgent demand of experimentalists for theoretical interpretation of their data. Also, in some cases, these computational efforts can be used to provide data that would be currently impossible or impractical to obtain experimentally. This development has been an essential element in the phenomenal growth in this area of materials science. More specifically, the advent of accurate self-consistent (local) spin density functional (LSDF) calculations for surfaces, interfaces, and multilayers means that theory is no longer limited to simple, parameter-dependent models. These complex systems are of growing interest because the reduced symmetry, lower coordination number, and availability and role of highly localized surface and interface states offers the possibility of inducing new and exotic phenomena and promotes the possibility of new device applications. pdf S0883769400062412a.pdf
