Abstract
For magnetic field measurements with magnetoelectric sensors sensitivities for AC magnetic fields in the femto-Tesla range are desired. Important factors for the necessary signal/noise ratio are extrinsic noise sources such as vibrations and acoustics. In this paper a concept to reduce the noise contributions from these sources is suggested and investigated. It is shown that by connecting two magnetoelectric sensors with pico-Tesla sensitivity in a tuning fork structure the noise level caused by acoustic and vibrational coupling can be strongly reduced.
