| Abstract: | The soft magnetic properties of CoFeNiSiB amorphous alloy ribbon as sensing material were measured and analyzed.By the field-annealing heat treatment in air,a good asymmetric giant magneto-impedance effect(AGMI)has been obtained.A sensitive AGMI magnetic sensor was developed utilizing the field-annealed amorphous ribbon as sensing element,and the performance of the sensor was tested in open-loop and closed-loop conditions.The results indicate that the sensor shows a better sensitivity in the open-loop testi... |
