Abstract

Magnetic sensor made from giant magneto impedance effect (GMI) in amorphous wire always has negative feedback loop. This increases manufacturing difficulty and consumption of sensor. To solve the problem, a special structure of magneto impedance (MI) element was designed to eliminate the interference of high frequency pulse. High sensitive magnetic detector was made of the key single chip. Experiment results show that the detector has good linearity and high sensitivity within the range from 1 Oe to 1 Oe. The resolution of the detector reaches 10 nT. The detector could be used to detect small magnetic target and common magnetic target in far distance.

Key words： amorphous wire; GMI effect; magneto impedance element; magnetic detection; high sensitivity
