This thesis is devoted to the study of the electron spin properties for optoelectronic and spintronic applications of different GaAs-based semiconductor systems: GaAsN, GaAsBi, and InGaAs.The investigation of the spin properties of dilute nitride GaAsN-based semiconductors is centered on the properties of the hyperfine interaction between the electron and the nuclei at the paramagnetic centers naturally present in these compounds. The study is carried out, in the temporal domain, by a photoluminescence-based pump-probe technique and taking advantage of the spin-dependent relaxation mechanism via deep paramagnetic centers in GaAsN bulk. We demonstrate a novel detection scheme of the coherent electron-nuclear spin oscillations related to the...
