Abstract : Giant magneto2impedance effect s have been discovered in FeCoSiB amorphous and nanocrystalline wires. These effect s have giant sensitivity. Close attention has paid to it by schol2 ars in lot s of count ries , since their great promising prospect s in the application of sensor technolo2? gy. In this article , the sources of giant magneto - impendance effect s are int roduced briefly. And research development s of the effect s and their applications in amorphous and nanocrystalline soft magnetic alloy in recent years are summaried. The future applications are also described.
Key words :amorphous ; nanocrystalline ; Fe2based magnetic alloy ; giant magneto2impedance
