This study explores spin waves in 3D magnetic gyroids, revealing localized excitations and field-dependent responses. These findings pave the way for 3D magnonic metamaterials and radio frequency filters.
Area of Science:
- Physics
- Materials Science
Background:
- Magnonics traditionally focuses on planar systems.
- Three-dimensional (3D) nanostructures offer new possibilities for magnonic devices.
Purpose of the Study:
- To investigate spin wave dynamics in 3D magnetic gyroid nanostructures.
- To explore the potential of gyroids as metamaterials for signal processing.
Main Methods:
- Micromagnetic simulations were employed to model spin wave behavior.
- Ferromagnetic resonance measurements were used to experimentally validate simulation results.
Main Results:
- Collective spin wave excitations were found to localize within the gyroid network.
- The gyroid's ferromagnetic response demonstrated sensitivity to static magnetic field orientation, linked to crystallographic alignment.
- Multidomain gyroid films exhibit properties of magnonic materials with effective magnetization dependent on filling factor.
Conclusions:
- 3D magnetic gyroids possess unique spin wave dynamics.
- Gyroid nanostructures show promise for applications in 3D magnonics, spintronics, and radio frequency filters.

Qualitatively, any spin plus-half nucleus polarizes the spins of its electrons to the minus-half state. Consequently, the paired electron in the hydrogen–carbon bond must...

The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...
