Spin Wave Power Flow and Caustics in Ultrathin Ferromagnets with the Dzyaloshinskii-Moriya Interaction

Reference: J.-V. Kim, R. L. Stamps, and R. E. Camley, Phys. Rev. Lett. 117, 197204 (2016). We examined how the Dzyaloshinskii-Moriya interaction (DMI) influences the flow of spin waves in ultrathin films using analytical theory and micromagnetics simulations. With a point source field excitation, we find a number of different propagation regimes, such as caustics […]

Narrow Magnonic Waveguides Based on Domain Walls

Reference: F. Garcia-Sanchez et al., Phys. Rev. Lett. 114, 247206 (2015). By using spin wave theory and micromagnetics simulations, we have shown that localized eigenmodes of magnetic domain walls can act as efficient waveguides for spin waves in ultrathin films. This work has just appeared in Physical Review Letters. Last modified 23/06/15
