图7 (a)常温下Mn标样品的W波段连续波EPR谱线. 测试虚线框内信号的峰峰值作为信号强度. (b)磁场偏共振下的噪声谱. 微波频率为94.04 GHz，微波功率为2.8 mW，调制场幅度为4.4 G@100 kHz，时间常数为100 ms

Fig. 7 (a) W-band continuous wave EPR spectra of Mn(II) in GaO powder at room temperature. The peak to peak amplitude of the signal within the dashed box is measured as the signal strength. (b) Noise signal measured at off resonance. The MW frequency is 94.04 GHz with an input power of 2.8 mW. The modulation amplitude is 4.4 G@100 kHz. The time constant is 100 ms
