本文研究了微波辐射频率失谐量对金刚石中氮空位中心单电子自旋的影响。快速傅里叶变换表明,Ramsey条纹由与14 N核自旋超精细相互作用产生的三个分量组成,如果不考虑这三个分量的相位项,Ramsey条纹就不能得到很好的解释。每个相位由微波频率失谐和谐振拉比频率以及π/2脉冲确定。
We investigate the Ramsey fringes of a single electron spin of the nitrogen-vacancy center in diamond with different microwave radiation frequency detunings. The fast Fourier transform demonstrates that the Ramsey fringes consist of three components caused by hyperfine interaction with 14N nuclear spin, and the Ramsey fringes cannot be well explained without the phase term of the three components, which has not been mentioned before. Each phase is determined by the microwave frequency detuning and the resonant Rabi frequency as well as the π/2 pulse.
