Handbook on the Physics and Chemistry of Rare Earths

by K.A. Gschneidner, Jean-Claude G. Bunzli, Vitalij K. Pecharsky

Overview

Volume 20 completes the second decade of volumes in this series and focuses on the physical aspects of metallic compounds. Research efforts on metallic rare earth compounds started in earnest about 50 years ago and received a significant boost with the discovery of the RCo5 permanent magnets about 12 years later. During this time much has been learned about the structure as well as the electrical, magnetic and thermal properties of approximately 2500 binary rare earth metallic compounds. However, if one considers the possible true ternary compounds and possible pseudo-binary ternary alloys formed by mixing two binary compounds, there is still a wealth of knowledge to be obtained from these still-to-be discovered materials. This volume makes a start in this direction.

Chapter one deals with the Fermi surfaces of rare earth (Y, La, Ce,Pr, Nd, Sm, Gd and Yb) intermetallic compounds. It begins with an introduction to the relevant theories required to describe the electrons near the Fermi surface and then to the basic experimental techniques to study these surfaces. The main portion of the chapter is devoted to a comparison of the experimental results with the band structure calculations for a large number of compounds.Chapter two examines the world of thin films of rare earth metals, alloys and compounds. The three main topics covered are the pure metals themselves, metallic alloys and compounds, and metalloid compounds. The next chapter is devoted to hydrogen in metals and their binary compounds RH2 and RH3. One of the critical problems is the purity of the starting rare earth metal itself because phase relations can be greatly affected by impurities and attention istherefore paid to the preparation of specimens and the phase diagrams. Structural properties, kinetics and thermodynamic behavior, as well as electronic, magnetic and thermal properties are reviewed as well. Also examined is the profound influence of hydrogen on the magnetic properties by the mediation of RKKY interaction in these materials. The final chapter is an update on the magnetic behaviors of lanthanide intermetallic compounds, anarea which has seen many new developments in the last 15 years. The chapter is divided into two main parts. Part one is devoted to 3d magnetism where both the 3d metal and lanthanide element contribute to the magnetic behavior, and the second part is concerned with lanthanide magnetism itself.

About the Author

Jean-Claude Bünzli (he/him) is an Honorary Professor emeritus at the EPFL where he founded the Laboratory of Lanthanide Supramolecular Chemistry He earned a degree in chemical engineering in 1968 and a PhD in 1971 from the Swiss Federal Institute of Technology, Lausanne (EPFL). After two years at the University of British Columbia as a teaching postdoctoral fellow (photoelectron spectroscopy) and one year at the Swiss Federal Institute of Technology in Zürich (physical organic chemistry) he was appointed in 1974 as assistant-professor at the University of Lausanne. He launched a research program on the coordination and spectroscopic properties of f-elements and was promoted to full professor of inorganic and analytical chemistry in 1980. During 2009-2013 he was also a World Class University professor at Korea University (South Korea) at the WCU Center for Next Generation Photovoltaic Devices. In 2016, he has been appointed as adjunct professor at the Haimen Institute of Science and Technology (Haimen, Jiangsu, P.R. China) which is a satellite campus of Hong Kong Baptist University. His research interests deal with various aspects of luminescent lanthanide coordination and supramolecular compounds, developing luminescent bioprobes and bioconjugates for the detection of cancerous cells with time-resolved microscopy as well as luminescent materials for various photonic applications, including solar energy conversion. In 1989, he founded the European Rare Earths and Actinide Society which coordinates international conferences in the field and for which he is presently acting as president.

V.K. Pecharsky received a combined BSc/MSc degree in Chemistry (1976) and a PhD degree in Inorganic Chemistry (1979) from Lviv State University (now Ivan Franko National University of Lviv) in Ukraine. He held a faculty appointment at the Department of Inorganic Chemistry at Lviv State University between 1979 and 1993, after which he moved to Ames, Iowa, where he became a staff member at the U.S. Department of Energy Ames Laboratory. In 1998 he accepted a faculty position at the Department of Materials Science and Engineering at Iowa State University, while remaining associated with Ames Laboratory. He was named an Anson Marston Distinguished Professor of Engineering in 2006. He also serves as a Faculty Scientists, Field Work Project Leader, and Group Leader at Ames Laboratory.
While in Lviv, V. Pecharsky was studying phase relationships and crystallography of ternary intermetallic compounds containing rare earths. After moving to Ames his research interests shifted to examining composition-structure-physical property relationship of rare-earth intermetallic compounds. Together with Karl Gschneidner, Jr., he discovered a new class of materials that exhibit the giant magnetocaloric effect in 1997, triggering worldwide interest in caloric materials and caloric cooling, which promises to become an energy-efficient, environmentally-friendly alternative to conventional vapor-compression approach. Today his research interest include synthesis, structure, experimental thermodynamics, physical and chemical properties of intermetallic compounds containing rare-earth metals; anomalous behavior of 4f-electron systems; magnetostructural phase transformations; physical properties of ultra-pure rare earth metals; caloric materials and systems; hydrogen storage materials; mechanochemistry, mechanically induced solid-state reactions and mechanochemical transformations.
He organized the 28th Rare Earth Research Conference in Ames, Iowa in 2017. He serves as co-editor of the Handbook on the Physics and Chemistry of Rare Earths and senior editor of the Journal of Alloys and Compounds. He has published over 500 WOS papers (>22 600 cites, h factor = 60).
