Band Structure calculation of thin film YIG based magnetic crystal — •Tobias Stückler, Ping Che, Sa Tu, and Haiming Yu — Spintronics Interdisciplinary Center, Department of Electronic and Information Engineering, Beihang University Beijing, 100191, China

Magnonic crystals (MCs) are a new class of magnetic nanostructures. They become the key to provide the possibility of studying frequency bands and band gaps of magnetic materials. MCs can be used to develop new applications, like spin filters. We study spin wave propagation in MCs based on magnetic insulator thin film YIG and report simulation of band information and forbidden band gap for frequencies tuned by the crystal lattice and the materials.
