“…In the absence of interfacial torques, thresholds for parametric processes in metal films are ordinarily prohibitively high due to high magnetic dissipation in metals. However, interface-driven anti-damping torques can substantially reduce the effective magnetic damping, greatly reducing this power threshold [Urazhdin et al ., 2010; Edwards et al ., 2012]. …”

This article reviews static and dynamic interfacial effects in magnetism, focusing on interfacially-driven magnetic effects and phenomena associated with spin-orbit coupling and intrinsic symmetry breaking at interfaces. It provides a historical background and literature survey, but focuses on recent progress, identifying the most exciting new scientific results and pointing to promising future research directions. It starts with an introduction and overview of how basic magnetic properties are affected by interfaces, then turns to a discussion of charge and spin transport through and near interfaces and how these can be used to control the properties of the magnetic layer. Important concepts include spin accumulation, spin currents, spin transfer torque, and spin pumping. An overview is provided to the current state of knowledge and existing review literature on interfacial effects such as exchange bias, exchange spring magnets, spin Hall effect, oxide heterostructures, and topological insulators. The article highlights recent discoveries of interface-induced magnetism and non-collinear spin textures, non-linear dynamics including spin torque transfer and magnetization reversal induced by interfaces, and interfacial effects in ultrafast magnetization processes.

We use space-resolved magneto-optical spectroscopy to study the influence of spin Hall effect on the excitation and propagation of spin waves in microscopic magnonic waveguides. We find that the spin Hall effect not only increases the spin-wave propagation length, but also results in an increased excitation efficiency due to the increase of the dynamic susceptibility in the vicinity of the inductive antenna. We show that the efficiency of the propagation length enhancement is strongly dependant on the type of the excited spin-wave mode and its wavelength.

“…(102) Because, processing with spin waves allows easy tunability by the external magnetic field (25) and low energy cost tunability via electric field or stress when combined with magnetoelectric or magnetostrictive materials. (103,104) It can also be influenced by electric current (105,106), facilitating the transfer of magnetic momentum without charge transport; thus, magnon spintronics (107,108) gives a chance for competing with electronics and spintronics, which is based on charge transport. Moreover, magnetic structures offer possibility for playing with the magnetic configuration.…”

Magnonic crystals can be regarded as the magnetic counterpart of photonic crystals, with spin waves acting as information carriers. Thus, magnonic crystals are magnetic materials with periodic distribution of the constituents or periodic modulation of some magnetic parameters (e.g., saturation magnetization or magnetocrystalline anisotropy), or other parameters relevant to the propagation of spin waves (e.g., external magnetic field, film thickness, stress, or a surrounding of the homogeneous ferromagnetic film). The spin waves propagating in magnonic crystal have a form of Bloch waves, and the dispersion relation includes frequency bands allowing spin wave propagation and frequency band gaps, forbidden for spin wave propagation. By adjusting relevant parameters of the magnonic crystal or external fields, the spectrum of spin waves can be tuned and the flow of spin waves can be tailored in the way unavailable with homogeneous media. The new physical effects occurring in magnetic nanostructures with periodic pattern and prospective applications of magnonic crystals, especially in integrated microwave devices and for processing information at microwave frequencies, drive the new fields of magnonics and magnon spintronics.
