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...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | 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.
