Exploiting nonlinearity in a Coupled-Core Fluxgate Magnetometer

Coupling-induced oscillations are a feature that appears to be universal in coupled systems that are (individually) described by bi-or multi-stable potential energy functions U(x); these properties are being exploited in a new class of dynamical sensors being developed by us. Here, we describe one of these devices, a coupled core fluxgate magnetometer (CCFM), whose operation is underpinned by this dynamic behavior.
