Magnetic excitation in geometrically confined systems exhibit many unique and interesting properties. This book reviews magnetic nanoparticles, layered magnets and in quasi-one-dimensional magnets, their properties and applications for data storage or creating engineered composite materials.
In this book, author Gary Wysin provides an overview of model systems and their behaviour and effects, and is intended for advanced students and researchers in physics, chemistry and engineering interested in confined magnetics. It is also suitable as an auxiliary text in a class on magnetism or solid state physics. Previous physics knowledge is expected, along with some basic knowledge of classical electromagnetism and electromagnetic waves for the latter chapters.

In this book, author Gary Wysin provides an overview of some model systems and their behaviour and effects. Intended for advanced students and researchers in physics, chemistry and engineering, which are interested in confined magnetics either to form a purely theoretical point of view or to consider properties for potential novel applications. It is also suitable as an auxiliary text in a class on magnetism or solid state physics. Some previous physics knowledge is expected, including the understanding of classical Hamiltonian mechanics, basic ideas about quantum spin, and statistical physics. Some of the later chapters consider electromagnetic effects in magnets in metals, where some basic knowledge of classical electromagnetism and electromagnetic waves is needed.
