This book is an application of quantum mechanics and statistical mechanics to the field of magnetism. A large part of the book is devoted to a detailed treatment of the connections between electronic properties and magnetism, and how they differ in the various known magnetic systems. Current trends are exposed and explained for a large class of alloys and compounds. The modern field of artificially layered systems - known as multilayers - and their industrial applications are dealt with in detail. The book also relates the rich thermodynamic properties of magnets to the ab initio results...

Electrons and ions have been used for over 40 years as probes to investigate the fascinating properties of helium liquids. The study of the transport properties of microscopic charge carriers sheds light on superfluidity, on quantum hydrodynamics, on the interactions with collective excitations in quantum liquids. The structure of the probes themselves depends on their coupling with the liquid environment in a way that gives further insight into the microscopic behavior of the liquid in different thermodynamic conditions, such as in the superfluid phase, in the normal phase, or near the...

Electrons in solids behave like microscopic bar magnets, and in certain solids these align to produce macroscopic magnetizations. This book deals with the dynamics of this magnetization field. It addresses questions of microscopic mechanism only to the extent that residual interactions of the magnetic moments with other degrees of freedom of the host solid affect the dynamics, particularly the dissipative aspects. Several of these damping mechanisms are evaluated here for their effect on the equations of the magnetization dynamics. This dynamics is intrinsically nonlinear. This is important...

During the last decade our expertise in nanotechnology has advanced considerably. The possibility of incorporating in the same nanostructure different organic and inorganic materials has opened up a promising field of research, and has greatly increased the interest in the study of properties of excitations in organic materials. In this book not only the fundamentals of Frenkel exciton and polariton theory are described, but also the electronic excitations and electronic energy transfers in quantum wells, quantum wires and quantum dots, at surfaces, at interfaces, in thin films, in...

The book deals with the propagation and absorption of high frequency w aves in plasmas. The text collects in a structured and self-contained way the basic knowledge on the broad and varied behavior of plasma wav es, adopting the microscopic kinetic description of the plasma as unif ying principle. The internal coherence of the theory is explicitly str essed, and interesting physical phenomena peculiar to plasmas are disc ussed in detail, including collisionless damping of waves, the develop ment of stochasticity in the interactions of charged particles with el ectromagnetic waves, and...

This is the first book to present the principles of operation of both the Paul and Penning ion traps - powerful experimental devices in which charged particles can be confined indefinitely in a small region of space so that experiments may be performed on them. This new and exciting method has applications not only in atomic physics, frequency standards, and collisional studies, but also in analytical mass spectrometry, making this book highly relevant not only to physicists but also to chemists. Written by a leading authority in the field, it is unique in bringing together detailed...

An invaluable, up-to-date reference aid for investigators and researchers, this two-volume work develops the principles and concepts of statistical physics and quantum chemistry that are the basis for the interpretation of experimental data. These volumes build on the author's now standard text, Theory of Neutron Scattering (Oxford University Press, 1971), and include expanded coverage of nuclear scattering, with many sections completely rewritten and updated, and many previously unpublished experimental calculations. With a greatly expanded bibliography including 200 new references, this...

Most stars show some degree of magnetic activity, from the familiar variations in the Sun's magnetic field, which coincide with the sun-spot cycle, to the enormous magnetic fields created by rotating neutron stars. Magnetic fields are also a potential key to understanding the formation of new stars and the behavior of galactic nuclei. This book by one of the leading figures in stellar magnetism provides an authoritative survey of this rapidly developing field. Based on a lifetime of research, the book places stellar magnetism in a broad astronomical scope and provides a thorough, well-argued...
