    Stress reconfigurable tunable magnetoelectric resonators as magnetic sensors
    Kiser, Jillian; Finkel, Peter; Gao, Junqi; Dolabdjian, Christophe; Li, Jiefang; Viehland, Dwight D. (AIP Publishing, 2013-01-01)
    We report a magnetoelastic effect in doubly clamped ferromagnetic magnetostrictive Metglas resonators with electrically and magnetically reconfigurable frequency response. The field-induced resonance frequency shift is due to magnetostrictive strain, which is shown to have a strong dependence on uniaxial stress. Here, we demonstrate that this magnetic field induced behavior can be used as the basis for a simple, tunable, magnetoelectric magnetic field sensor. The effect of tension on the field dependent magnetostrictive constant and the sensor sensitivity is examined, and the equivalent magnetic noise floor of such a sensor is estimated.
