Abstract :
A stress-driven magnetoelastic amorphous metal ribbon probe is presented which demonstrates equivalent noise floors of 18 pT/ square root (Hz) for the magnetic field, 23 pT/cm/ square root (Hz) for the first order field gradient, and 43 pT/cm2/ square root (Hz) for the second order field gradient.
