Nonlinear dynamics and stability of a microcantilever for Magnetic Resonance Force Microscopy

The focus of this paper is on the nonlinear dynamics of a resonator model proposed for measurement of electron spin via Magnetic Resonance Force Microscopy. The resonator model augmented by the Bloch equations for the magnetization is analyzed numerically. Orbital instabilities include coexisting solutions and lengthy chaotic transients that occur below a homoclinic jump-to-contact threshold.
