The metal and semiconductor-based magnetoelectronics were studied in terms of coherent spin accumulations. Semiconductor-based magnetoelectronics is motivated by the prospect of integrating new functionalities with conventional semiconductor electronics. The polarization state was monitored by time-dependent Farady rotation measurements of the coherent spin precession in an applied magnetic field. It is observed that in the first 50 ps or so, the photoexcited carriers screen the Schottky barrier efficiently.
