Abstract
We have studied propagating spin-flip waves excited in a two dimensional electron gas by angle resolved magneto-Raman spectroscopy. The damping rate of these excitations follows a quadratic law, as a function of q, and the group velocity is linearly dependent with q. Consequently the propagation length presents a maximum for a given q. We have estimated and analyzed the maximum propagation length showing that the spin waves are drastically attenuated in a microscopic distance, even in the intrinsic regime.
