摘要：
We report the systematic change of the domain wall (DW) motion mechanism depending on the ratio of composition x in two-dimensional Co1-xFex ferromagnetic systems (0.0 <= x <= 1.0) by means of the direct domain observation. Interestingly, as the Fe composition x increases, the DW motion mechanism becomes changed from the stochastic behavior with random DW sizes to the thermally activated behavior with specific DW sizes. This result could be understood by the change of the magnetic angular symmetry from a 2-fold one to a 4-fold one with increasing the Fe composition, responsible for the change of the DW type.
