Daniel Khomskii
Daniel Khomskii graduated from Moscow University in 1962. Starting in 1965, he worked in the Theoretical Department of the Lebedev Physical Institute of the Russian Academy of Science in Moscow. There, he defended his Ph.D. in 1969. In 1980, he obtained a second doctoral degree–the Russian equivalent to the German Habilitation or a professorship in the US. From 1992 to 2003, he was a Professor at Groningen University in the Netherlands and since 2003, he has been a guest Professor in Köln (Cologne University) in Germany. His main research interests are the theory of systems with strongly correlated electrons, metal-insulator transitions, magnetism, orbital ordering (“Kugel-Khomskii model”) and superconductivity. He is a recently elected Fellow of the American Physical Society and has published roughly 300 papers over the course of his career.
Classifying multiferroics: Mechanisms and effects
The field of multiferroics has greatly expanded in the last few years, particularly with the discovery of so many different types of multiferroic materials. This review organizes these materials according to the microscopic origin of their properties and explores how we can expect to find similar multiferroic behavior in systems that we have been studying all along.
