“…The combination of low magnetic damping, soft magnetization behavior, and a band gap of 2.66 eV, making it a good insulator, qualify this material for microwave applications such as filters [3,4] or sensors [5,6]. Its low absorption in the optical and near-infrared wavelength region, combined with a magneto-optic Faraday effect (FE), render this material interesting for telecommunication devices such as magneto-optic isolators [7,8].…”
