Samenvatting

A time-resolved study of the photoinduced magneto-optical response of InP in the spectral range nearby the spin-orbit split-off exciton transition shows both bleaching of the split-off exciton transition and splitting of the exciton spin sublevels. The bleaching relaxes with a decay of 10 ps due to energy redistribution of the photoexcited carriers. The splitting of the spin sublevels shows a two-exponential decay with characteristic times of 20 ps and 200 ps, respectively. These times are related to the relaxation of the spin polarization of the electrons in the conduction band.
