Abstract
In this paper, we discuss the nonlinear behavior of a model rf superco nducting quantum-interference-device magnetometer consisting of a macr oscopic quantum object which is coupled reactively to a linear classic al oscillator. We demonstrate that chaotic solutions can be found in t he oscillator for the ground and first excited states of the quantum o bject over a wide range of parameters, including those relevant to exp erimental systems.
