- Abstract: Temperature-dependent nitrogen-vacancy (NV)-center relaxometry is an
established tool to characterize paramagnetic molecules near to a sensing
diamond, gaining momentum in different fields of science. However, recent
results indicate that conversion between NV-center charge states impedes these
measurements and influences the results for the $T_1$ time. While the
temperature dependence of NV centers' $T_1$ time is well-studied, additional
contributions from temperature-dependent charge conversion during the dark time
may further affect the measurement results. We combine temperature-dependent
relaxometry and fluorescence spectroscopy at varying laser powers to unravel
the temperature dependence of charge conversion in nanodiamond for biologically
relevant temperatures. While we observe a decrease of the $T_1$ time with
increasing temperatures, charge conversion remains unaffected by the
temperature change. These results allow the temperature dependent performance
of $T_1$ relaxometry without further consideration of temperature dependence of
charge conversion.

We report the existence of a sizeable quantum tunnelling splitting between the two lowest electronic spin levels of mononuclear Ni complexes.
The level anti-crossing, or magnetic clock transition, associated with this gap has been directly monitored by heat capacity experiments.
The comparison of these results with those obtained for a Co derivative, for which tunnelling is forbidden by symmetry, shows that the clock transition leads to an effective suppression of intermolecular spin-spin interactions.
