A dual-axis, high-sensitivity atomic magnetometer Project supported by the National Natural Science Foundation of China (Grant Nos. 61227902, 61673041, and 61374210), the National Key R & D Program of China (Grant No. 2016YFB0501601), and the Academic Excellence Foundation of Beihang University (BUAA) for PhD Students. |
(color online) Frequency response of the dual-axis AM. Two magnetic fields, whose frequency varies from 1 Hz to 55 Hz, are applied to By and Bx in order to test the bandwidth of Ch1 and Ch2 AMs. |
