Dissipation characteristics of quantized spin waves in nano-scaled magnetic ring structures
The spatial profiles and the dissipation characteristics of spin-wave quasieigenmodes are investigated in small magnetic Ni81Fe19 ring structures using Brillouin light scattering microscopy. It is found, that the decay constant of a mode decreases with increasing mode frequency. Indications for a contribution of three-magnon processes to the dissipation of higher-order spin-wave quasi-eigenmode...
متن کاملTuning of chaotic surface spin waves in a magnetic-film feedback ring via the ring gain
This paper reports on experimental data on the controlled tuning of chaotic surface spin waves in a magnetic-film active feedback ring. The chaotic behavior of these waves arises through three-wave nonlinear interactions. With a change in the ring gain, two chaotic regimes were observed. One corresponds to the situation where only one ring eigenmode was excited in the ring, while the other corr...
متن کاملQuantized spin waves in the metallic state of magnetoresistive manganites.
Spin wave measurements have been carried out in ferromagnetic (F) La(1-x)(Sr,Ca)(x)MnO(3) with x(Sr) = 0.15, 0.175, 0.2, 0.3, and x(Ca) = 0.3. In all q directions, close to the zone boundary, the spin wave spectra consist of several energy levels, with the same values in the metallic and the x approximately 1/8 doping ranges. For x(Sr) = 0.15, the data are quantitatively interpreted in terms of...

15 صفحه اولSpin waves in disordered magnetic systems
Long-wavelength spin waves in disordered magnetic systems have been investigated. In the framework of the Heisenberg model with magnetic dipole and exchange interactions between spins it is found that an additional longitudinal spin wave mode appears. This mode is characterized by variations of the value of the magnetic moment density. In order to analyse influence of the magnetic disorder on s...
