Coherent Magnetization Precession in GaMnAs induced by Ultrafast Optical Excitation
J. Qi, Y. Xu, N. Tolk +3
We use femtosecond optical pulses to induce, control and monitor magnetization precession in ferromagnetic Ga0.965Mn0.035As. At temperatures below ~40 K we observe coherent oscilla…

Near-bandgap wavelength-dependent studies of long-lived traveling coherent longitudinal acoustic phonon oscillations in GaSb/GaAs systems
J. K. Miller, J. Qi, Y. Xu +6
We report first studies of long-lived oscillations in optical pump-probe measurements on GaSb-GaAs heterostructures. The oscillations arise from a photogenerated coherent longitudi…
