Graded-index magnonics
The wave solutions of the Landau–Lifshitz equation (spin waves) are characterized by some of the most complex and peculiar dispersion relations among all waves. For example, the spin-wave (“magnonic”) dispersion can range from the parabolic law (typical for a quantum-mechanical electron) at short...

| description |
The wave solutions of the Landau–Lifshitz equation (spin waves) are characterized by some of the most
complex and peculiar dispersion relations among all waves. For example, the spin-wave (“magnonic”) dispersion
can range from the parabolic law (typical for a quantum-mechanical electron) at short wavelengths to the
nonanalytical linear type (typical for light and acoustic phonons) at long wavelengths. Moreover, the longwavelength
magnonic dispersion has a gap and is inherently anisotropic, being naturally negative for a range of
relative orientations between the effective field and the spin-wave wave vector. Nonuniformities in the effective
field and magnetization configurations enable the guiding and steering of spin waves in a deliberate manner and
therefore represent landscapes of graded refractive index (graded magnonic index). By analogy to the fields of
graded-index photonics and transformation optics, the studies of spin waves in graded magnonic landscapes can
be united under the umbrella of the graded-index magnonics theme and are reviewed here with focus on the challenges
and opportunities ahead of this exciting research direction. |
