Abstract:
New method for the detection of magnetic resonance signals versus temperature is
developed on the basis of the temperature dependence of the spin Hamiltonian
parameters of the paramagnetic system under investigation. The implementation of this
technique is demonstrated on the nitrogen-vacancy (NV) centers in diamonds. Single NV
defects and their ensembles are suggested to be almost inertialess temperature sensors.
The hyperfine structure of the $^{14}$N nitrogen nuclei of the nitrogen-vacancy center
appears to be resolved in the hyperfine structure characteristic to the hyperfine interaction
between NV and N$_{s}$ center (substitutional nitrogen impurity) in the ODMR
spectra of the molecular NV–N$_{s}$ complex. Thus, we show that a direct
evidence of the two-way transfer of a nitrogen nuclear spin hyperfine interaction in
coupled NV–N$_{s}$ pairs was observed. It is shown that more than 3-fold
enhancement of the NV ODMR signal can be achieved by using water as a collection
optics medium.
