Quartz tuning fork—A potential low temperature thermometer in high magnetic fields

M. Clovečko and P. Skyba,

We present the performance of commercial quartz tuning forks (QTFs) operating at resonance frequencies of 32 kHz, 77 kHz, and 100 kHz in the temperature range below 1 K and in high magnetic fields up to 7.5 T. We show that characteristics of the quartz tuning forks, in particular, the normalized QTF resonance frequency, manifest a universal temperature dependence, which is independent of the magnetic field strength. This feature makes the QTFs very promising low temperature thermometers in high magnetic fields in the temperature range below 1 K having the B/T ratio up to 1000. We also discuss the physical origin of the observed dependencies.
