TLDR
Spin-wave properties have been calculated for multilayered structures consisting of alternating ferromagnetic and nonmagnetic layers, as well as for all-ferromagnetic structures, fully taking into account magnetic interface anisotropies and exchange contributions.Abstract:
Spin-wave properties have been calculated for multilayered structures consisting of alternating ferromagnetic and nonmagnetic layers, as well as for all-ferromagnetic structures, fully taking into account magnetic interface anisotropies and exchange contributions. In the crossing regime of dipolar modes and exchange modes, the gap width is strongly influenced by the amount of interface anisotropy. In the case of all-magnetic multilayered structures, a new type of collective spin-wave excitation arising from coupled exchange modes is predicted.read more

Micro-focused Brillouin light scattering: imaging spin waves at the nanoscale
TL;DR: The optical method of Brillouin light scattering (BLS) spectroscopy is a well established tool for the characterization of spin waves as discussed by the authors, which is the inelastic scattering of light from spin waves and confers several benefits: the ability to map the spin wave intensity distribution with high sensitivity as well as the potential to simultaneously measure the frequency and the wave vector and, therefore, the dispersion properties.

Forbidden frequency gaps in magnonic spectra of ferromagnetic layered composites
TL;DR: In this article, the spin wave spectra in layered composite materials are computed by means of a transfer matrix method with evidence for the existence of numerous frequency gaps, and essential properties of these spectra are successfully explained within the framework of approximate models of independent films or an effective medium, according to the strength of the magnetization and exchange contrasts.
