Spin-Wave Relaxation in a Quantum Hall Ferromagnet
PACS: 73.21.Fg, 73.43.Lp, 78.67.De
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.
