The magneto-optic imaging technique is a powerful tool for visualizing electron spin dynamics in
semiconductors. We employed time- and spatially-resolved magneto-optic Kerr measurements to
investigate spin transport with dynamic dots, which are produced by surface acoustic waves (SAWs)
propagating in GaAs/AlGaAs quantum wells. Two-dimensional images of the electron spin flow reveal
acoustically controllable spin precession behavior. The phenomena will provide the flexibility needed
for spin manipulation in future spintronics applications.
