Edited by two pioneers of magneto-optics, this book is designed to provide graduate students and researchers with an introductory state-of-the-art review of recent developments in this subject. The field encompasses important areas in solid-state physics, chemical physics and electrical engineering. The book deals with optical spectroscopy of paramagnetic, antiferromagnetic, and ferromagnetic materials, photo-induced magnetism and their applications to opto-electronics.

Magneto-optics describes in general any interaction between electromagnetic radiation and a material which is magnetized. The book gives a concise but comprehensive introduction to theory, calculus, and typical experimental set-up used in magneto-optics. It includes a variety of practice problems with detailed solutions. The focus lies on the spectral range between near-infrared and near ultraviolet light because it is easily accessible in experiment using standard quartz optics.

Certain magnetic materials have optical properties that make them attractive for a wide variety of applications such as optical switches. This book describes the physics of one class of such magnetooptic materials, the insulating antiferromagnets. The authors summarize recent results concerning the structure, optical properties, spectroscopy, and magnetooptical properties of these materials. In particular, they consider magnetic phase transitions, symmetry effects, the linear magnetooptical effect, magnons, spectroscopic study of spin waves, photoinduced magnetic effects, and the effects of impurities.

The Advanced Study Institute on "Theoretical Aspects and New Developments in Magneto-Optics" was held at the University of Antwerpen (R.U.C.A.), from July 16 to July 28, 1979. The Institute was sponsored by NATO. Co-sponsors were: Agfa-Gevaert (Belgium), A.S.L.K. (Belgium), Bell Telephone Mfg. CO. (Belgium), Esso Belgium, Generale Bankmaatschappij (Belgium), General Motors (Belgium), I.B.M. (Belgium), Kredietbank (Belgium), Metallurgie Hoboken-Over pelt (Belgium), National Science Foundation (U.S.A). A total of 60 lecturers and participants attended the Institute. Scope of the Institute The magneto-optic phenomena are due to the change of the polarizability of a substance as a result of the splitting of the quantized energy bands. Most of these phenomena were discovered during the second half of this century. The understanding of the magneto-optical effects of all kinds, however, was brought by the advent of quantum mechanics, and since then important progress has been made in many fields of experimental methods and techniques.

This book presents experimental studies on emergent transport and magneto-optical properties in three-dimensional topological insulators with two-dimensional Dirac fermions on their surfaces. Designing magnetic heterostructures utilizing a cutting-edge growth technique (molecular beam epitaxy) stabilizes and manifests new quantization phenomena, as confirmed by low-temperature electrical transport and time-domain terahertz magneto-optical measurements. Starting with a review of the theoretical background and recent experimental advances in topological insulators in terms of a novel magneto-electric coupling, the author subsequently explores their magnetic quantum properties and reveals topological phase transitions between quantum anomalous Hall insulator and trivial insulator phases; a new topological phase (the axion insulator); and a half-integer quantum Hall state associated with the quantum parity anomaly. Furthermore, the author shows how these quantum phases can be significantly stabilized via magnetic modulation doping and proximity coupling with a normal ferromagnetic insulator. These findings provide a basis for future technologies such as ultra-low energy consumption electronic devices and fault-tolerant topological quantum computers.
