Spin waves (SW) are the excitation of the spin system in a ferromagnetic condensed matter body. They are collective excitations of the electron system and, from a quasi-classical point of view, can be understood as a coherent precession of the electrons' spins. Analogous to photons, they are also referred to as magnons indicating their quasi-particle character. The collective nature of SWs is established by the short-range exchange interaction as well as the non-local magnetic dipolar…

Spin-wave excitation and critical angles in a hybrid photon-magnon-coupled system
We studied “strongly enhanced” excitations of magnetostatic spin-waves in a hybrid magnon-photon-coupled system consisting of an inverted split-ring resonator and an yttrium iron garnet film. The

Spin-Wave Amplification and Lasing Driven by Inhomogeneous Spin-Transfer Torques.
It is shown that an inhomogeneity in the spin-transfer torques in a metallic ferromagnet under suitable conditions strongly amplifies incoming spin waves, which could facilitate the field of magnonics, which aims to utilize spin waves in logic and data-processing devices.

A field theory to study the dynamics of long wavelength exchange spin wave excitations on honeycomb nanoribbons characterized by armchair edge boundaries and the Néel antiferromagnetic ordering state finds the spatial variation of the amplitudes of the evanescent exchange spin waves across the finite widths of the nan oribbons, is found to be strongly dependent on the system magnetic anisotropy and its width.
