This paper presents a reduced order model including the resonator and the mechanical moment induced by the thin film on the resonator. The model development is presented as well as its experimental validation with four magnetometer prototypes. This model is then used to investigate the optimization of the thin film position on the resonator as well as the advantages of various shapes of resonators.
This paper presents models developed through analytical or numerical computation and finite-element analysis to improve the resolution of a new kind of vibrating magnetometers. This peculiar magnetometer uses the piezoelectric transduction to actuate a quartz resonator at its resonance frequency taking advantage of the high $Q$ factor of a quartz resonator to achieve high resolution. The magnetic...
This paper presents the preliminary work to demonstrate the feasibility of a miniature resonator based magnetometer. This magnetometer consists of a thin film of ferromagnetic material sputtered on a cantilever with a magnetic moment aligned along the length of the cantilever. As the resonator vibrates under a magnetic field, the magnetostatic interaction induces a torque on the cantilever that stiffens...
