Abstract

All-optical pump-probe detection of magnetization precession has been performed to investigate Gilbert damping in several types of Ni 80Fe20 films. The frequency and decay time of magnetization precession depended on pump fluence. At low pump fluence, Gilbert damping constants, derived from the magnetic field dependence on frequency and decay time of magnetization precession, were identical to values obtained from X-band ferromagnetic resonance within the experimental errors.
