摘要
Modulation and deflection of light by lattices of parallel stripe domains in epitaxial garnet films is investigated. If the resonance oscillation of the domain lattice is excited by rf fields, the deflected light is modulated at the resonance frequency which can be tuned by external bias fields to more than 2 GHz. This is the highest frequency of an oscillating domain lattice reported thus far. Modulation frequencies and wall oscillation amplitudes are determined experimentally. Calculated resonance frequencies are in agreement with observation if the quality factor of the film is greater than one.
