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. Both theoretical principles and main equivalent magnetic noise sources are explained. Sensor performance is given and compared with measurements. The experimental setup and limiting factors, such as the coupling factor between the magnetization and the sensed signal, are also evaluated and analyzed. That leads to the illustration of the system performance in term of noise and sensitivity.
