研究了微波场对电子自旋的控制。对铜线天线产生的近磁场进行了实验测量和理论模拟，得到了最佳的天线长度和位置。利用532 nm连续波激光在室温下激发金刚石中氮空位（N-V）中心后的荧光变化，验证了微波场可以有效地控制N-V中心的自旋。
Controlled manipulation of the electron spin by means of a microwave field is investigated. The near magnetic field generated by a copper wire antenna is measured experimentally and simulated theoretically, and the optimum antenna length and position are obtained. By measuring the change in the fluorescence of nitrogen-vacancy (N-V) centers in diamond after excitation with a 532 nm continuous wave laser at room temperature, it is verified that the spin of the N-V center can be effectively controlled by the microwave field.
