摘要
成功研制了磁光记录薄膜擦写疲劳特性测试系统。系统中利用串联谐振法 ,获得了重复频率为 1 k Hz、峰值磁场达 4 0 k A/m的高频双向脉冲磁场 。
A system for measuring the fatigue behavior of the magneto optic recording thin films is introduced In this system, a series resonance method is proposed and a frequency of 1kHz and a magnetic peak field of 40kA/m can be achieved At the same time the intensity dividing readout method is adopted, it can eliminate the fluctuation of the readout laser power
