We combine magneto-optical imaging and a magnetic field pulse technique tostudy domain wall dynamics in a ferromagnetic (Ga,Mn)As layer withperpendicular easy axis. Contrary to ultrathin metallic layers, the depinningfield is found to be smaller than the Walker field, thereby allowing for theobservation of the steady and precessional flow regimes. The domain wall widthand damping parameters are determined self-consistently. The damping, 30 timeslarger than the one deduced from ferromagnetic resonance, is shown toessentially originate from the non-conservation of the magnetization modulus.An unpredicted damping resonance and a dissipation regime associated with theexistence of horizontal Bloch lines are also revealed.
