Image of FIG. 1.
FIG. 1.

(a) Topological image taken by an atomic force microscope. The width of the strips was with a periodicity. (b) Local magnetic hysteresis loop measured on the strip. (c) Magnetic hysteresis loop measured on the unpatterned area of the sample.

Image of FIG. 2.
FIG. 2.

Time-resolved domain images of periodic magnetic strips under a constant magnetic field. The reversed domains were formed in the beginning and then propagated along the strips in time.

Image of FIG. 3.
FIG. 3.

Time-resolved domain images of a magnetic strip with a constant time step. The strength of the magnetic field was , smaller than the coercive field of . The domain wall propagation in a constant speed and the pinning are clearly seen from the figure.

Image of FIG. 4.
FIG. 4.

The position of the domain wall front with respect to the elapsed time , measured from the images shown in Fig. 3. The linear fitting lines guide the wall propagation. The inset shows another stepwise process seen from other strips.

Image of FIG. 5.
FIG. 5.

(a) The magnetic field dependence of the wall propagation speed. The dashed line shows the best fit using Eq. (1). (b) The wall pinning time of the pinning site located at “B” in Fig. 3, with respect to the strength of an applied magnetic field. The dashed line shows the best fit using Eq. (2).
