This account of the principles and applications of magnetooptics is aimed at the graduate physicist and electrical engineer, but assumes no specialist knowledge of magnetooptics. The text is divided into three main sections: the principles of magnetooptics, providing the historical background, with an emphasis on introducing practical considerations through examples taken from real-life situations; a survey of magnetooptic materials; and applications of magnetooptics in practical devices, including modulators, switches, memory devices and waveguides.

This text provides an introduction to the whole field of permanent magnetism. It contains a comprehensive but concise treatment of the fundamental theory underlying permanent magnetism, and illustrates applications with modern permanent magnetic materials. Each chapter contains worked examples to reinforce applications. Detailed mathematics and tabular data on material properties are treated in the appendices.
