Abstract

We have developed a novel ferromagnetic resonance measurement technique using the magneto optical Kerr effect. The measurement technique uses microwave-frequency, intensity-modulated light to stroboscopically measure the Kerr angle due to the magnetization precession. We demonstrated that this stroboscopic magneto optical Kerr effect provides a frequency domain and phase sensitive FMR measurement. It is found that the measurement is proved to be sensitive enough to detect the precessing magnetization with the precession cone angle below 1̊.
