Abstract

The temperature dependence of the magnetic-resonance spectra of nitrogen-vacancy (NV) ensembles in the range of 280–330 K was studied. Four samples prepared under different conditions were analyzed with NV concentrations ranging from 10 ppb to 15 ppm. For all samples, the axial zero-field splitting (ZFS) parameter D was found to vary significantly with temperature, T, as dD/dT=74.2(7)kHz/K. The transverse ZFS parameter E was nonzero (between 4 and 11 MHz) in all samples, and exhibited a temperature dependence of dE/(EdT)=1.4(3)×104K1. The results might be accounted for by considering local thermal expansion. The temperature dependence of the ZFS parameters presents a significant challenge for diamond magnetometers and may ultimately limit their bandwidth and sensitivity.
