摘要:

通过结合微波和射频激发场,控制负电荷氮空位中心的自旋态在强磁场中最为有效,其中能级反交叉(LAC)现象显著。然而,在零磁场中也能利用LAC来控制自旋态并激发窄共振用于计量应用。本文报告了在零磁场下利用双频(微波+射频)共振激发在金刚石体NV中心ODMR谱中出现的磁场无关共振,并讨论其特性。

英文摘要:

The methods for controlling spin states of negatively charged nitrogen-vacancy centers using a combination of microwave (MW) or radiofrequency (RF) excitation field for electron spin transitions and RF excitation field for nuclear spin transitions are most effective in strong magnetic fields where level anti-crossing (LAC) occurs. However, LAC in zero field can also be used to control spin states, as well as to excite narrow resonances for metrological application. In this paper we present magnetically independent resonances arising in the ODMR spectra of NV centers in bulk diamond under two-frequency (MW+RF) resonant excitation in zero magnetic field, and discuss their specificity.
