Anomalous Rare Earths and Actinides: Valence Fluctuation and Heavy Fermions focuses on the characteristics, reactions, transformations, technologies, and processes involved in the study of anomalous rare earths and actinides. The selection first offers information on lanthanides and actinides and electronic structures in cerium monopnictides. Topics include rare earth metals with fluctuating valencies, 'normal' rare earth metals, and band calculation and Fermi surface. The text then elaborates on neutron scattering studies of anomalous rare earth compounds, including magnetic neutron scattering measurements, stability and localization of magnetic moments, and condensed state. The manuscript examines the transport properties of cerium monochalcogenides and pressure-volume relationships of cerium monochalcogenides and monopnictides. The text also ponders on the theory of anisotropic magnetic behavior in hybridizing actinide systems; band hybridization effects on indirect magnetic coupling of localized moments; and neutron scattering from transuranium materials. The selection is a dependable reference for readers interested in the research on anomalous rare earths and actinides.

Handbook on the Physics and Chemistry of Rare Earths: Including Actinides, Volume 55, the latest release in a continuous series of books covering all aspects of rare earth science, including chemistry, life sciences, materials science and physics, presents comprehensive, broad, up-to-date, critical reviews written by highly experienced, invited experts. The series, which was started in 1978 by Professor Karl A. Gschneidner Jr., combines and integrates both the fundamentals and applications of these elements, with this release including chapters on Low Coordinate f-element Complexes and Organometallic Lanthanide SMMs. - Presents up-to-date overviews and new developments in the field of rare earths, covering both their physics and chemistry - Contains individual chapters that are comprehensive and broad, along with critical reviews - Provides contributions from highly experienced, invited experts

The understanding of electronic behaviour in solids when (some of) the valence electrons have both localized and band-like characteristics is one of the central problems of physics and chemistry in the second half of this century. Many advances have indeed been made using highly sophisticated techniques and concepts. Our objectives in bringing together specialists from different areas was cross-fertilization of ideas and redefinition of bottlenecks and problems. The testimony of the participants and the book which follows indicate a fair degree of success. This book is a record of discussions aimed at digestion and reassessment of some of the recent major advances in our understanding of narrow bands. Note that we expressly asked participants to give a short readable account of the major problems in their field and not to emphasize their latest results to be as "technical" as they might be in a normal scientific article. We did not ask for complete reviews of what was going on in the field and this book should not be read as such. Neither should it be approached as the sort of educational text which the NATO ASI proceedings are supposed to be. We have tried to produce a useable account of a workshop in which an attempt was made to define real problems and to distinguish them from illusory problems.
