Current-induced multiple domain wall motion modulated by magnetic pinning in zigzag shaped nanowires
Source abstract
Abstract
Using micromagnetic simulation, we investigate the current-induced multiple domain wall motion (CIDWM) in zigzag nanowires with different bar angles (θ=90°, 120° and 150°). Two dynamic processes of single DWM and double DWM are found in different regimes of current density identified by two thresholds in all zigzag nanowires. The decreasing threshold current is found in the zigzag nanowires with increased bar angles, indicating the angular-dependence of the magnetic pinning. This work suggests a possibility of manipulating the single/multiple DWM in future DW devices by introducing the shape anisotropy.
