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 zincbleude 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.
