【Abstract】 A new kind of magnetic sensor was developed based on Giant Magneto-impedance effect(GMI)of Fe76Si7.6B9.5P5C1.9 amorphous alloy thin ribbon.The GMI characteristics of Fe76Si7.6B9.5P5C1.9 amorphous alloy thin ribbon,magnetic sensor circuit and performance test of the magnetic sensor were discussed.The results showed that the sensor had good repeatability,almost no hysteresis,good linearity,a wide range of linear measurement(-651.14~325.57 A/m),and sensitivity of 3.49 mV/(A·m-1) etc.What important was that linearity was preserved in weak magnetic field.更多还原
