Abstract
We study spin wave relaxation in quantum Hall
ferromagnet regimes. Spin-orbit coupling is considered as a factor
determining spin nonconservation, and external random potential as
a cause of energy dissipation making spin-flip processes
irreversible. We compare this relaxation mechanism with other
relaxation channels existing in a quantum Hall ferromagnet.
