Magneto-optics of II-VI diluted magnetic semiconductors

摘要

K, S. Krishnan's pioneering contributions to the magnetism of condensed matter included insightful studies on crystals with 3d transition metal ions as one of the constituents. We illustrate, with examples of striking magneto-optic phenomena, how the incorporation of such ions in the tetrahedrally coordinated II-VI semiconductors (the ZI-VI diluted magnetic semiconductors) has created a splendid scientific opportunity. These II-VI magnetic semiconducting alloys exhibit huge excitonic Zeeman splittings which in turn result in a giant Faraday rotation and an impressively large Voigt birefringence. [References: 29]
