Abstract
We demonstrate optically broadband piezo-optomechanical magnetometry, integrating a Mach-Zehnder interferometer with magnetostrictive material for magnetic responsivity and piezoelectric material for actuation/control, with broadband sensitivity ~1 nt/√hz up to ~500 kHz and ~10 pT/√Hz at mechanical resonance.
