摘要：
We are dealing with the fast domain wall dynamics in glass-coated microwires. Three main parameters are recognized that results in a very high domain wall velocity that can reach more than 10 km/s. Firstly, it is a low Gilbert damping that decreases the domain wall damping. Secondly, it is the presence of two perpendicular anisotropies (that can be modified by proper thermal treatment). Finally, the radial domain structure shields the domain wall from the pinning at the surface.
