There are four folders containing raw data of the Kerr rotation signals

1) three folders includes the data obtained at 10-GHz optical excitation for three excitation powers 95mW, 55mW and 30mW;

In each folder there are files with the raw signals which names correspond to the external magnetic field values in mT. A background file, which is included into each folder, contains the background signal of the system, which has to be subtracted from the raw signals in order to obtain the correct waveform of the Kerr rotation signal. The signals were measured in a differential scheme and the calibration coefficient between the measured voltage and the Kerr rotation angle (in radians) is a=5E-4 (KR angle = a*voltage). Each folder includes also the 'RMS values' file, which contains the processed data with the Root Mean Square amplitudes for each signal.

2) one folder includes the data obtained at 80-MHz optical excitation for single excitation power of 250 mW. The second part of the file name indicates the strength of the external magnetic field. The calibration coefficient between the measured voltage and the Kerr rotation angle (in radians) is a=7E-3 (KR angle = a*voltage).

包含四个文件夹，分别存储克尔旋转信号的原始数据。

其中三个文件夹包含在10 GHz光激发下获取的数据，针对三种激发功率：95 mW、55 mW 和 30 mW。每个文件夹内含有与外部磁场值（单位：mT）相对应的原始信号文件。每个文件夹中还包含一个背景文件，其中存储了系统的背景信号，该信号需从原始信号中减去，以获得正确的克尔旋转信号波形。信号采用差分方案测量，电压与克尔旋转角（弧度）之间的校准系数为 a=5E-4（KR角度 = a*电压）。每个文件夹还包含一个包含每个信号均方根振幅的处理后数据的 'RMS值' 文件。

第二个文件夹包含在80 MHz光激发下获取的数据，针对单个激发功率 250 mW。文件名的第二部分表示外部磁场的强度。电压与克尔旋转角（弧度）之间的校准系数为 a=7E-3（KR角度 = a*电压）。
