Abstract

We have recently demonstrated an AC magnetic field sensing scheme using a simple continuous-wave optically detected magnetic resonance of nitrogen-vacancy centers in diamond. This scheme is based on electronic spin double-resonance excited by continuous microwave and radiofrequency (RF) fields. Here, we measure and analyze the double-resonance spectrum and magnetic field sensitivity for various microwave and RF frequencies. We observe a clear anticrossing of RF-dressed electronic spin states in the spectrum and estimate the bandwidth to be approximately 5 MHz at a center frequency of 9.9 MHz.
