Statistical Mechanics Of Magnetic Excitations: From Spin Waves To Stripes And Checkerboards [Kõva köide]

Rastelli (materials for electronics and magnetism, National Center of Scientific Research, Paris and physics, U. of Parma, Italy) examines the elementary excitations in magnetic periodic structures, the spin waves or magnons, which are shown to behave like an ideal Bose gas at low temperature and an interacting Bose system at higher temperature. Some of the chapters are appropriate for an upper-level undergraduate course on magnetism, and other for a graduate course. In either case students should be able to begin conducting active research in magnetism using both analytic calculations and Monte Carlo simulations.

The aim of this advanced textbook is to provide the reader with a comprehensive explanation of the ground state configurations, the spin wave excitations and the equilibrium properties of spin lattices described by the Ising–Heisenberg Hamiltonians in the presence of short (exchange) and long range (dipole) interactions.The arguments are presented in such detail so as to enable advanced undergraduate and graduate students to cross the threshold of active research in magnetism by using both analytic calculations and Monte Carlo simulations.Recent results about unorthodox spin configurations such as stripes and checkerboards should then excite theoreticians in the field of magnetism and magnetic material research.
