High-frequency and high-field optically detected magnetic resonance of nitrogen-vacancy centers in diamond
Abstract
We present the development of an optically detected magnetic resonance (ODMR) system, which enables us to perform the ODMR measurements of a single defect in solids at high frequencies and high magnetic fields. Using the high-frequency and high-field ODMR system, we demonstrate 115 GHz continuous-wave and pulsed ODMR measurements of a single nitrogen-vacancy (NV) center in a diamond crystal at the magnetic field of 4.2 Tesla as well as investigation of field dependence (0-8 Tesla) of the longitudinal relaxation time (T1) of NV centers in nanodiamonds.
