Abstract
Piezoelectric quartz tuning forks are investigated for use as force sensors in dynamic mode scanning probe microscopy at temperatures down to 1.5 K an d in magnetic fields up to 8 T. The mechanical properties of the forks are extracted from the frequency dependent admittance and simultaneous interfer ometric measurements. The performance of the forks in a cryogenic environme nt is investigated. Force-distance studies performed with these sensors at low temperatures are presented.
