Abstract(in English) | We have measured high frequency response of optical magnetic field sensors using Bi-substituted rare-earth iron garnet films up to 1 GHz.The sesor has a 150 MHz frequency bandwidth.A resonance peak was observed at around 100 MHz in the spectrum.The frequency response decreases gradually toward 1 GHz.The cause of the resonance phenomenon can be understood from domain wall resonance.The sensor with higher saturation magnetic field has a wider frequency bandwidth.As a result, we have found that the opticl current transformers using the sensors have enough performance to detect the surge current such as μs order response. |
