Abstract :
Summary form only given. A parametric magnetic sensor is a flux-response type and its sensitivity is higher than that of any other flux-response type sensor. Also, it is an oscillation type sensor like an MI sensor. The frequency of the oscillation voltage is operated as that of the carrier voltage. The output voltage of the sensor is detected as an envelope voltage of the amplitude-modulated oscillation voltage. In this paper a low frequency parametric magnetic sensor for detection of a local magnetic field is described. We show that the sensor has very high sensitivity.
