Description:
Author(s): Luyi Yang, J. D. Koralek, J. Orenstein, D. R. Tibbetts, J. L. Reno, and M. P. Lilly We use phase-resolved transient grating spectroscopy to measure the propagation of spin helices in a high mobility n -GaAs/AlGaAs quantum well with an applied in-plane electric field. At relatively low fields helical modes crossover from overdamped excitations where the spin-precession period exceeds... [Phys. Rev. Lett. 109, 246603] Published Wed Dec 12, 2012
