On the possibility of classical vacuum polarization and magnetization
Sébastien Fumeron, Fernando Moraes, Bertrand Berche
It is common practice to take for granted the equality (up to the constant ) of the electric displacement () and electric () field vectors in vacuum.…
Experimental analysis of the spin-orbit coupling dependence on the drift velocity of a spin packet
N. M . Kawahala, F. C. D. Moraes, G. M. Gusev +2
Spin transport was studied in a two-dimensional electron gas hosted in a wide GaAs quantum well occupying two subbands. Using space and time Kerr rotation microscopy to image drift…
Acceleration of the precession frequency for optically-oriented electron spins in ferromagnetic/semiconductor hybrids
F. C. D. Moraes, S. Ullah, M. G. A. Balanta +6
Time-resolved Kerr rotation measurements were performed in InGaAs/GaAs quantum wells nearby a doped Mn delta layer. Our magneto-optical results show a typical time evolution of the…
Robustness of spin coherence of the exciton bound to neutral donor states in multilayer system
S. Ullah, F. C. D. Moraes, G. M. Gusev +2
We address the temperature influence on the precessional motion of electron spins under transverse magnetic field, studied in a GaAs/AlGaAs triple quantum wells, using pump-probe K…
Gate control of the spin mobility through the modification of the spin-orbit interaction in two-dimensional systems
M. Luengo-Kovac, F. C. D. Moraes, G. J. Ferreira +5
Spin drag measurements were performed in a two-dimensional electron system set close to the crossed spin helix regime and coupled by strong intersubband scattering. In a sample wit…
