The dynamic properties of the magnetic domain walls in amorphous glass‐covered microwires were studied. The samples was Joule annealed with an alternate current at different frequencies and the dynamic behaviour of the samples were studied at different applied stresses. The Landau–Lifshitz–Gilbert damping parameter and the domain wall mobility have shown that the dynamic response can be improved by increasing the annealing current frequency.
