Tailoring Bloch-type Stripe Domain Wall by Spin–orbit Torque for Reconfigurable Magnonic Waveguides
Tóm tắt
Efficient manipulation of magnetic textures by spin–orbit torque is of great significance to spintronic and magnonic technologies. Here, using micromagnetic simulations, we exploit the dynamics of a Bloch-type stripe domain wall in a magnetic nanowire induced by the spin-Hall effect associated with a ferromagnet/heavy metal structure. Our numerical results demonstrate that, contrary to the Néel-type stripe domain wall, the stripe Bloch domain wall varies its internal spin configuration in response to the applied electric current and, in the meantime, travels toward an edge of the nanowire. The higher the current density applied, the nearer the domain wall approaches the edge. Thereby, the stripe Bloch domain wall is movable to any desired position with respect to the edge by fine-tuning the current density and/or its action time. These discoveries will find application in reconfigurable spin-wave channeling based on magnetic domain walls.
