Pinning-dependent vortex wall oscillations in a one dimensional NiFe nanowire
Domain wall dynamics under the action of applied forces are crucial for future device concepts. We present the specific features of the vortex wall (VW) under the combination of an applied force, collective pinning, and magnetic anisotropy in a patterned rectangular shaped NiFe nanowire. We show the...

| description | Domain wall dynamics under the action of applied forces are crucial for future device concepts. We present the specific features of the vortex wall (VW) under the combination of an applied force, collective pinning, and magnetic anisotropy in a patterned rectangular shaped NiFe nanowire. We show the experimental evidence of VW propagation and the VW-based spin wave (SW) oscillation with intrinsic pinning barriers. As the VW was excited by a microwave antenna, the SW modes exhibited a localized or periodic oscillation feature with well-defined frequencies, which opens up the possibility to control data transport and processing by SW features. |
