Abstract

The optical Faraday effect is the most evident time-nonreversible phenomenon, caused by an external magnetic field and leading to nonreciprocal polarization rotation. However, even without an external magnetic field the spin orbit coupling within a molecule may cause time-nonreversible effects, such as light depolarization in incoherent molecular and Raman scattering.^1·3 We believe that in crystal optics time-nonreversible behavior without an external magnetic field is also possible, specifically in zincblende semiconductors,^3·4 and especially in dilute magnetic semiconductors where the spin effects are very pronounced. The first observation of linear and non-linear time-nonreversible effects in the optics of diluted magnetic semiconductors is the subject of the present paper.
