Abstract : A thin film vector magnetometer is configured to produce an output that varies linearly with the component of an externally applied magnetic field in the plane of a thin film chip portion thereof along a predefined sensitivity axis. The sensitivity and linear dynamic range of the thin film vector magnetometer are intimately related to each other through a bias field supplied by a bias magnet portion of the device. The bias field also defines the sensitivity axes of the magnetometer which is orthogonal to the unidirectional bias field supplied by the bias magnet.
