Opis

This book is designed to provide graduate students and research beginners with an introductory review of recent developments in the field of microscopic magneto-optics. The field contains the most important subjects in solid state physics, chemical physics, and electronic engineering. Microscopic studies of magneto-optics stem from those of ligand-field spectra of paramagnetic ions in solids and liquids, which are also well known to have brought developments in material research for solid-state lasers. As the introductory chapter of this monograph, Chap. 1 deals with the fundamental properties of ligand-field spectra in useful solids. Chapter 2 is on elementary excitations such as magnons and excitons in magnetically ordered crystals, a central aspect of recent developments in microscopic magneto- optics. Chapter 3 concerns Raman spectroscopy accompanying magnetic ex- citations of high energies in strongly correlated electron systems, which are related to high Tc superconductors. Chapter 4 is on recent developments in the studies of non-linear optical effects, citing experiments for Cr20 and de- 3 scribing a microscopic theory for its second harmonic generation. In Chap. 5, after introducing a phenomenological theory of the Faraday and Kerr effects, we present a microscopic theory based on the ligand-field theory and discuss the future developments. Chapter 6 concerns diluted magnetic semiconduc- tors, discussing formation, magnetic properties, and quantum confinement effects of magnetic polarons. Chapter 7 is also on diluted magnetic semi- conductors, emphasizing the importance in growing new magnetic semicon- ductors and in studying their remarkable magneto-optical properties.

The book is designed to provide graduate students and research novices with an introductory review of recent developments in the field of magneto-optics. The field encompasses many of the most important subjects in solid state physics, chemical physics and electronic engineering. The book deals with (1) optical spectroscopy of paramagnetic, antiferromagnetic, and ferromagnetic materials, (2) studies of photo-induced magnetism, and (3) their applications to opto-electronics. Many of these studies originate from those of ligand-field spectra of solids, which are considered to have contributed to advances in materials research for solid-state lasers.
