Magnon excitations in vortex-state nanorings
The magnon mode excitation spectrum is calculated using the linearized Landau–Lifshitz equations applied to the ring in the vortex ground state. A combination of analytical techniques with numerical evaluation of integrals is used to obtain the mode frequency with the effective magnetostatic volu...

| description |
The magnon mode excitation spectrum is calculated using the linearized Landau–Lifshitz equations
applied to the ring in the vortex ground state. A combination of analytical techniques with
numerical evaluation of integrals is used to obtain the mode frequency with the effective magnetostatic
volume charge as a small perturbation. In general, the modes can be classified according to
radial number n and azimuthal number m. It is shown that the frequency increases as n increases,
and the frequency decreases as m increases.
