Quartz tuning forks as sub-kelvin thermometers in high magnetic fields

The determination of low temperatures in high fields is a difficult task. The resonances of quartz tuning forks are a promising solution.
Experimental measurements of low temperatures in high magnetic fields are challenging, as many thermometric parameters are sensitive to high fields, and calibrations to account for such effects are non-trivial. To address this limitation, Marcel Človečko and Peter Skyba sought to find a temperature-dependent physical parameter unaffected by large magnetic fields.
