| contents | This research chapter provides a comprehensive overview of ferromagnetic gyroidal nanostructures, combining a review of state-of-the-art research with our new findings on their implications for 3D magnonics. Both static and dynamic magnetization studies show that non-trivial shape anisotropy, chirality, and inhomogeneous demagnetization fields influenced by specific crystallographic arrangements lead to multiple low-energy state magnetization textures, spin-wave mode localization, and controllable spin-wave propagation, highlighting the substantial potential of gyroidal nanostructures.
The review integrates insights into micro/nano texturing to elucidate the intricate relationships between gyroidal geometry, chirality, and their effective magnetic properties, especially at microwave frequencies. Our study of resonance frequencies in gyroid samples under rotational field manipulation further reveals the significant influence of geometric anisotropy on ferromagnetic resonance signal strength. This chapter establishes a fundamental understanding of ferromagnetic gyroidal nanostructures, paving the way for their future investigation in 3D magnonics. |
