A longitudinal nonlinear relaxation of magnetization following the ultrafast demagnetization is considered. As demonstrated, the fastest regime occurs for a small deviation of the magnetization from the equilibrium value. However, the relaxation time of strongly suppressed magnetization is substantially increased due to a nonlinearity of magnetic system.
Key words: ferromagnets, femtosecond laser pulse, ultrafast demagnetization, relaxation effects.
