Title: Resonating torque microbalance for in situ measurements of ferromagnetic films
Published: January 01, 2002
Abstract: We describe an instrument for in situ monitoring of the magnetic moment of a thin film during deposition with sub-monolayer sensitivity. The instrument measures the magnetic torque on a film as it is being deposited onto a microcantilever excited near its mechanical resonance. Dynamic feedback is used to balance the magnetic torque by applying a mechanical force at the base of the cantilever.
