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 materials research.
Contents:
- Magnetic Hamiltonians
- Spin Waves in Ferromagnets
- Interacting Spin Waves in Ferromagnets
- Feynman Diagrams Expansion in Ferromagnets
- Two-Magnon Bound States in Ferromagnets
- Perturbation Theory in Planar Ferromagnets
- Spin Waves in Non-Collinear Systems
- Spin Waves in Multilayers
- Spin Waves in Systems with Long Range Interaction
- Long Range Interactions in 2D Systems
Readership: Students and professionals interested in the fields of theoretical magnetism and magnetic material research.
Key Features:
- Many-body theory applied to magnetic insulators: the Green function approach is compared to the Feynman diagram expansion
- Two spin wave deviations from clusters to thermodynamic limit
- Stripe and checkerboard configurations
