Magnetic Materials and Devices for the 21st Century:
Stronger, Lighter, and More Energy Efficient

Dr. Oliver Gutfleisch
IEEE Distinguished Lecturer
Institute of Metallic Materials, Dresden, Germany

Abstract

   A new energy paradigm, consisting of greater reliance on renewable energy sources and increased concern for energy eff ciency in the total energy life-cycle, has accelerated research into energy-related technologies. Due to their ubiquity, magnetic materials play an important role in improving the effciency and performance of devices in electric power generation, conditioning, conversion, transportation, and other energy use sectors of the economy.
   This lecture focuses on the state-of-the-art hard and soft magnets and magnetocaloric materials, with an emphasis on their optimization for energy applications. Specif cally, the impact of hard magnets on electric motor and transportation technologies, of soft magnetic materials on electricity gen-eration and conversion technologies, and of magnetocaloric materials for refrigeration technologies, are discussed. The synthesis, characterization, and property evaluation of the materials, with an emphasis on structure–property relationships, are discussed in the context of their respective markets, as well as their potential impact on energy eff ciency. Finally, considering future bot-tlenecks in raw materials, options for the recycling of rare-earth intermetallics for hard magnets will be discussed.

Biography

Dr. Oliver Gutfleisch Oliver Gutfleisch received the diploma in materials science from the Technical University of Berlin, Germany. He completed the Ph.D. degree at the School of Metallurgy and Materials, University of Birmingham, U.K., in 1995 and continued his work there on rare earth-transition metal compounds for permanent magnet applications as a research fellow. He joined the Leibniz Institute of Solid State and Materials Research (IFW Dresden), Germany, in 1998 and is leading a research group on “Functional Materials for Sustainable Energy.” In 2007 followed the habilitation at the Technical University of Dresden. He is a Visiting Professor at the Imperial College London and NIMS Tsukuba. He has published more than 180 articles in refereed journals and has been granted several patents. His scientific interest is focused on new permanent magnets for power applications, solid state energy efficient magnetic cooling, ferromagnetic shape memory alloys, magnetic nanoparticles for biomedical applications, and solid state hydrogen storage materials with an emphasis on tailoring structural and chemical properties on the nanoscale. Dr. Gutfleisch is a member of the Technical Committee and the AdCom of the IEEE Magnetics Society and served on the program and publication committees of several MMM and MMM-Intermag conferences.
