Suppression of Barkhausen Noise in Magnetoresistive Sensors Employing AC Bias - Magnetics, IEEE Transactions on

  • Published 2004


A magnetic field rotating in the plane of a thin-film magnetoresistive sensor provides continuous saturation of the ferromagnetic material if the magnitude of the field was sufficiently large. This mode of excitation allows operation free of errors related to remanence and in the same time it helps in suppressing the Barkhausen noise. The experiment… (More)
