Photoinduced dyrotropy due to spin-density fluctuations of the free electrons in semiconductors
Danishevskii A. M., Perlin E. Yu.
An ultralinear dependence of the induced optical gyration in я-InAs on the electron density η in the с conduction band is observed. A 200 deg · cm/MW angle of rotation Θ is attained. The proposed theory of the phenomenon relates the region of rapid increase in θ (η) to the spin splitting of the с band and describes the observed effects of spatial dispersion.
