Abstract

Single crystals of Zn 1− x− y Hg x Mn y Te grown by a modified Bridgman method have been investigated by means of optical spectroscopy and the Faraday rotation techniques. It has been found that structural, optical and magnetooptical characteristics of the studied quaternary semimagnetic semiconductor with x=0.5, y=0.4 have good prospects for applications as sensing elements in magnetic field sensors. An advantage of the material, as compared with Cd 1− x Mn x Te, is its better performance in the range of laser wavelengths above 800 nm, for which cheap and low-noise laser diodes are available.
