Asymmetric dynamic behaviors of magnetic domain wall in trapezoid-cross-section nanostrip
Fig. 1. (a) The geometry and dimension of the trapezoid-cross-section nanostrip. The external magnetic field direction is denoted by the arrows on the top. A head-to-head transverse DW is initially positioned in the center of the nanostrip, and its direction is denoted by the arrows inside. The cross section of the nanostrip is shown at the bottom. (b) The schematic diagrams of the nanotube unrolled into a trapezoid-cross-section nanostrip when it is cut along the long axis.
