The relaxation of the excess magnetization, which is proportional to the Faraday rotation, does not follow the Nattermann-Vilfan theory in detail for this range of T and H. We explore other possible forms for the time dependence of the excess magnetization and use Monte Carlo techniques as an aid in the interpretation of the experimental data.
