Optically Detected Magnetic Resonance with
Nitrogen-Vacancy Spin Ensemble in Diamond Hyun Joon Lee1 and Jeong Hyun Shim1,2,* 1Korea Research Institute of Standards and
Science, Daejeon 34113, Republic of Korea 2Deparment of Medical Physics, University of Science and
Technology, Daejeon 34113, Republic of Korea Abstract We
report Optically-Detected Magnetic Resonance (ODMR) study on Nitrogen-Vacancy
(NV) centers in diamond. The experiment can easily be conducted with basic
optics and microwave components. A diamond crystal having a high-density NV
center is suitable for the ODMR study. The magnetic field dependence of ODMR
spectrum allowed us to determine the orientation of the diamond crystal. In
addition, we measured the variation of the ODMR spectrum as a function of the
excitation laser power. Thermal heating induced by optical absorption caused
the monotonic decrease of zero field splitting. The contrast of the ODMR peak,
however, increased and, then, began to decrease, indicating the optimal laser
power for recording the ODMR spectrum. |
