我们报告了模板辅助电沉积法生长的单个NiFe圆柱形纳米线的磁化结构。角各向异性磁阻测量结果表明，三维螺旋畴壁自然形成后，从饱和状态松弛。微磁学模拟支持螺旋畴壁的性质及其反转过程，其中涉及分裂的顺时针和反时针涡旋。当一个脉冲电流施加到纳米线，观察到的螺旋畴壁传播所需的最小电流密度，以克服其固有的钉扎。
We report on the magnetization configurations in single NiFe cylindrical nanowires grown by template-assisted electrodeposition. Angular anisotropic magnetoresistance measurements reveal that a three-dimensional helical domain wall is formed naturally upon relaxation from a saturated state. Micromagnetic simulations support the helical domain wall properties and its reversal process, which involves a splitting of the clockwise and anticlockwise vortices. When a pulsed current is applied to the nanowire, the helical domain wall propagation is observed with a minimum current density needed to overcome its intrinsic pinning.
