Abstract :A new weak current sensor using Fe72. 7CuNb2V1. 8 Si13. 5B9 nanocrystalline alloy materials made by means of amorphous annealing is investigated. The sensor has differential symmetric structure with single nanocrystalline core and double coils excited by multivibrator bridge. The principle of the sensor is analyzed and the signal processing circuit is designed.
Key words : amorphous annealing ; nanocrystalline alloy ; weak current sensor ; differential symmetric structure
