Abstract

Nowadays quartz tuning forks are commonly used for temperature measurements in experiments with liquid (both normal and superfluid) \(^3\)He. In most of the experiments pure \(^3\)He is used, but in some cases \(^4\)He is added in order to cover surfaces by a few monolayers of \(^4\)He. We report here measurements of influence of different \(^4\)He coverages on the fork resonance properties at different pressures. We have found that the presence of even small amounts of paramagnetic \(^3\)He on the fork surface may essentially change the temperature calibration.
