Snell’s Law for Spin Waves

, 2016
We report the experimental observation of Snell's law for magnetostatic spin waves in thin ferromagnetic Permalloy films by imaging incident, refracted, and reflected waves.

Effect of Substrate on Spin‐Wave Propagation Properties in Ferrimagnetic Thulium Iron Garnet Thin Films

Advanced Electronic Materials
Rare‐earth iron garnets have distinctive spin‐wave (SW) properties such as low magnetic damping and long SW coherence length making them ideal candidates for magnonics.

Enhanced magnetostatic modes in a nonuniform plasma

, 1981
Parametric excitation of the magnetostatic mode by finite-amplitude drift waves is considered. Both decay and modulational instabilities are analyzed. Expressions for the growth rates are obtained analytically.

Nano-Magnonic Crystals by Periodic Modulation of Magnetic Parameters

Magnetochemistry
Magnonic crystals are metamaterials whose magnon behavior can be controlled for specific applications. To date, most magnonic crystals have relied on nanopatterning and magnetostatic waves.

Band-pass filter based on magnetostatic surface waves, exciting by symmetric coplanar line

, 2016
An excitation of magnetostatic surface waves (MSSW) by symmetric coplanar transmission line was considered for the case, when coplanar line is placed at some distance from the ferrite film surface.

Excitation of magnetostatic spin waves in anisotropic ferromagnetic films, magnetized in arbitrary direction

, 2014
Exact analytical expressions for propagator of small-amplitude linear magnetostatic waves in ferromagnetic thin film between two antennae and their corresponding mutual impedance are obtained by solving the linearized torque equation of spin dynamics ...

Nonlinear signal processing by means of surface magnetostatic waves: solitons in metallized structures

, 2002
Nonlinear magnetostatic waves (MSWs) have recently received considerable attention for their potentialities in microwave signal processing through the generation of phenomena like modulation instability and solitons, typical of optical devices too.
