Abstract :
We experimentally study frequency shifts in quartz crystal resonators (QCRs) under quasi-static magnetic fields. It is found that the frequency shifts of the QCR are mainly caused by the magnetomechanical response of the holders of the resonator and the related stresses in the resonator. Understanding and prediction of this effect may be useful for reducing resonator frequency shifts or quasi-static electric/ magnetic field sensing.
