Observation of inter-Landau-level quantum coherence in semiconductor quantum wells
K. M. Dani, I. A. Cotoros, J. Wang +4
Using three-pulse four-wave-mixing femtosecond spectroscopy, we excite a non-radiative coherence between the discrete Landau levels of an undoped quantum well and study its dynamic…

Memory Effect in the Photoinduced Femtosecond Rotation of Magnetization in the Ferromagnetic Semiconductor GaMnAs
J. Wang, I. Cotoros, X. Liu +4
We report a femtosecond response in photoinduced magnetization rotation in the ferromagnetic semiconductor GaMnAs, which allows for detection of a four-state magnetic memory at the…

Ultrafast Enhancement of Ferromagnetism via Photoexcited Holes in GaMnAs
J. Wang, I. Cotoros, K. M. Dani +3
We report on the observation of ultrafast photo-enhanced ferromagnetism in GaMnAs. It is manifested as a transient magnetization increase on a 100-ps time scale, after an initial s…
