2D Hybrid Yttrium Iron Garnet Magnetic Sensor Noise Characterization

This paper deals with the noise characterization of a magnetic field hybrid sensor based on flux-gate-like magnetometer. In the used layout, a magnetic core, like an Yttrium-Iron-Garnet (YIG) thin film, is driven to saturation by a rotating magnetization field, which induces a modulated magnetic field. The latter is sensed, by means of one or more punctual sensors, as an image of the applied magnetic field vector components.
