Abstract
We have measured the high frequency response of optical magnetic field sensors using bismuth-substituted rare-earth iron garnet films up to 1 GHz. A resonance peak was observed in the frequency response spectrum, but flat response to 230 MHz was observed. The cause of the resonance phenomenon can be understood from domain wall resonance.
