  • Abstract
    A novel type of magnetometer is proposed. The magnetic field is measured via the magnetoelastic effect in amorphous magnetic ribbon material, using the phase of an ultrasonic shear wave. Preliminary measurements yield a sensitivity of 15nT with a 1 s time constant. Order-of-magnitude estimates indicate a potential sensitivity of less than 1 pT.
