Femtosecond Demagnetization and Hot Hole Relaxation in Ferromagnetic GaMnAs
J. Wang, L. Cywinski, C. Sun +3
We have studied ultrafast photoinduced demagnetization in GaMnAs via two-color time-resolved magneto-optical Kerr spectroscopy. Below-bandgap midinfrared pump pulses strongly excit…

Electrical expression of spin accumulation in ferromagnet/semiconductor structures
L. Cywinski, H. Dery, P. Dalal +1
We treat the spin injection and extraction via a ferromagnetic metal/semiconductor Schottky barrier as a quantum scattering problem. This enables the theory to explain a number of…
