  • Abstract
    In this paper, we present experimental results on the noise spectrum, which we used to investigate chaotic noise caused by nonlinear magnetic excitation. In addition, a newly designed sensor structure for possible suppression of noise and an increase in signal level is presented. High frequency carrier-type thin film sensors (also called GMI sensors) are expected to have a sub-pT resolution at room temperature when used for biomagnetic measurements.
