Review of the Book “magnetooptical Spectroscopy of the Rare-Earth Compounds: Development and Application”

Journal of Electromagnetic Analysis and Applications 2012年第5期4卷 216-217页

作者： I. S. Edelman L.V. Kirensky Institute of Physics Siberian Branch of Russian Academy of Sciences Krasnoyarsk Russia.

This book reviews and provides numerous theoretical calculations for the first time relevant to the optics and magneto-optics of the trivalent rare earth ions (RE3+) and their compounds. The RE3+ have unique spectroscopic properties that make them exceptionally attractive to both scientists, who probe the fundamental properties of these systems, and engineers, who develop these systems into photonic devices eagerly marketed in expanded technologies. Magneto-optical effects in compounds doped with RE3+ have been studied since the dawn of modern physics and have had a profound impact on their development in terms of practical opto-electronic devices. The authors of this new, exciting, and fresh text are world famous in this field, with over 150 years of experience in developing important theoretical and experimental contributions and over fifty years of more than 500 refereed publications in this field in the Soviet Union and the United States. They offer both a conceptual description of magneto-optical phenomena, as well as clear, detailed theoretical development published for the first time of many of the phenomena only briefly addressed in the literature. The book is based on the author’s original work in theoretical and experimental investigations in magneto-optics. Numerous graphs and simple examples model the phenomena described in the text, making it a highly desirable treatise for scientists beginning their studies in the field of magneto-optics.

Theory of Triple Magnetopolarons in Quantum-Dimensional Nanostructures

引用

American Journal of Analytical Chemistry 2013年第9期4卷 457-463页

A theory of triple magnetopolarons in an isolated quantum well in a strong magnetic field was developed. We study the behavior of the magnetooptical absorption peaks corresponding to the transitions of an electron at the Landau level with quantum numbers n ≥ 2. For n = 2 at the point of equality of cyclotron frequency and the frequency of optical phonon (LO), there is a cross of three terms of the electron-phonon system (the electron at the Landau level n = 2, the electron at n = 1, and the optical phonon and electron at n = 0 and two phonons), considered as a function of the cyclotron frequency. Interaction with phonons takes off the degeneracy of the terms and leads to three disjoint branches of the electron-phonon spectrum. The theory predicts that in the resonant magnetic field, the peak of magnetooptical absorption splits into three peaks, the intensity and position of which are dependent in a complex way on the magnitude of the magnetic field and the constant of the electron-phonon coupling.
