Title: Voigt effect in diluted magnetic semiconductors: Cd sub 1 minus x Mn sub x Te and Cd sub 1 minus x Mn sub x Se

Abstract

We report a giant Voigt effect in diluted magnetic semiconductors Cd{sub 1{minus}{ital x}}Mn{sub {ital x}}Te and Cd{sub 1{minus}{ital x}}Mn{sub {ital x}}Se and present an excitonic model that describes its dispersion and {ital M}{sup 2} dependence, {ital M} being the magnetization. We discuss the Voigt effect in Cd{sub 1{minus}{ital x}}Mn{sub {ital x}}Te (0.10{lt}{ital x}{lt}0.45), a zinc-blende diluted magnetic semiconductor, in the context of this model. In addition, we present experimental results for the Voigt effect in Cd{sub 1{minus}{ital x}}Mn{sub {ital x}}Se ({ital x}=0.26 and 0.31), a diluted magnetic semiconductor with wurtzite structure, where the effect is considerably more complicated due to its lower symmetry. Specifically, we present a striking anisotropy of the Voigt effect in Cd{sub 1{minus}{ital x}}Mn{sub {ital x}}Se, which depends on the relative orientation of the applied magnetic field with respect to the optic ({bold {cflx c}}) axis of the crystal.
