Thin Ferromagnetic Film-Based Two-Dimensional Magnonic Crystals

摘要

A new type of photonic crystals entitled "Magnonic Crystals (MC)" that exhibit forbidden gaps in the microwave spectrum of magnetostatic spin waves (MSW) are reported. The topography of the MCs that consist of two-dimensional (2-D) etched holes periodic structure in yttrium iron garnet films was studied by atomic force and magnetic force magnetometry. The propagation characteristics of spin waves in such 2-D MCs was measured and analyzed.
