We report the experimental observation of the pure anomalous Hall effect (AHE) in nonmagnetic zinc-blende semiconductors without application of the external magnetic fields. The AHE without any contribution from the ordinary Hall current originates from nonequilibrium magnetization induced by spin-polarized electrons generated by the circularly polarized light (s). We measure the pure AHE as a function of the external bias, crystal temperature and pumping s-photon energy. The results of their dependences are discussed.
