针对GHz频段的高频磁场传感器探头，采用液相外延技术制备薄膜，研究了高频区的铁磁共振现象。利用磁性石榴石的磁光（MO）效应制作了磁场分布成像传感器。然而，对于GHz频率范围内的高频磁场表征的应用，通常的MO测量难以检测磁场，因为磁性石榴石的磁导率降低。磁共振是在GHz量级的高频区产生磁矩、增强磁光效应的有效途径。为了详细了解高频磁场传感器的可能性，在脉冲强磁场中测量了高达315 GHz的高频远红外磁共振。考虑到磁光信号的灵敏度和磁共振强度，使用石榴石膜的磁光方法在100 GHz以下的频率是有效的。
For the sensor probe of high frequency magnetic field in GHz region, films were prepared by liquid phase epitaxy technique and ferromagnetic resonances were investigated in high frequency region. Magneto-optical (MO) effect of magnetic garnet was utilized for the imaging sensor of the magnetic field distribution. However, for the application to the characterization of high frequency magnetic field in the GHz frequency region, usual MO measurements are difficult to detect the magnetic filed as the decreasing of the permeability of magnetic garnet. Magnetic resonance is an effective way to induce magnetic moment and enhance the magnetooptical effect in high frequency region of GHz order. In order to understand the possibility of magnetic field sensor of high frequency in detail, far-infrared magnetic resonances were measured at the high frequencies up to 315 GHz in pulsed high magnetic field. Taking account into sensitivity of MO signals and magnetic resonance intensities, magnetooptical method using a garnet film is effective at the frequencies below 100 GHz.
