Abstract
Section titled āAbstractāThe response of the level anticrossing signal to a quasiresonant radio-frequency field, which appears in a zero magnetic field at nitrogen-vacancy (NV) color centers in diamond, is investigated. It is shown that the complex structure of this response can be explained by the Autler-Townes splitting. The possibility of controlling the parameters of the level anticrossing signal is considered. It is shown that the slope of the central resonance recorded in this structure upon low-frequency modulation of the external magnetic field can be 2.3 times higher than the slope of the resonance recorded in the absence of a radio-frequency field. Conclusions are drawn about the nature of the level anticrossing effect arising in zero field in NV color centers in diamond.
