Local control of spin flow in weak magnetic fields
J. -H. Quast, G. V. Astakhov, W. Ossau +4
We demonstrate that optical illumination strongly influences spin transport in n-type GaAs. Specifically, increasing the power density of optical spin pumping results in a signific…
Non-thermal photocoercivity effect in a ferromagnetic semiconductor
G. V. Astakhov, H. Hoffmann, V. L. Korenev +7
We report a photoinduced change of the coercive field, i.e., a photocoercivity effect (PCE), under very low intensity illumination of a low-doped (Ga,Mn)As ferromagnetic semiconduc…
Time-resolved and continuous-wave optical spin pumping of semiconductor quantum wells
G. V. Astakhov, M. M. Glazov, D. R. Yakovlev +4
Experimental and theoretical studies of all-optical spin pump and probe of resident electrons in CdTe/(Cd,Mg)Te semiconductor quantum wells are reported. A two-color Hanle-MOKE tec…
