[7p-PB7-25] Characteristic of spin waves in Fibonacci magnonic crystals
Keywords:metamaterial, spin waves, magnonic crystals
Spin-wave spin current is expected to be applied to low power super energy saving information processing devices, because it can suppress heat generation without flow of electrons. We study the manifestation of topological edge states in magnonic crystals with quasi-periodic structure. The topological edge states have strong propagation characteristics against disturbance. The permissible range of the quality of the ferromagnetic material and the fabrication accuracy of the artifictial structure widens, and is expected to realize robust and cost effective spin-wave devices.
