Giant Magneto-Impedance Behaviour in Ferro-Magnetic Materials

Mitra, A and Panda, A K (2002) Giant Magneto-Impedance Behaviour in Ferro-Magnetic Materials. In: Proceedings of the Indo-Malaysian Joint Workshop(WAM-2002), 12-13 March, 2002, National Metallurgical Laboratory, Jamshedpur.



The ferromagnetic amorphous and nanocrystalhne materials exhibited a new phenomenon called Giant magneto-impedance (GMI). In this phenomenon these materials exhibited a sensitive change in an AC voltage with the application of a small DC magnetic field. GUI properties were investi-gated for four different compositions of amorphous and nanocrystalline ferromagnetic alloys for ribbon and wire samples. The impedance behaviour was strongly affected by magnetostriction of the materials. In nearly zero magneto-strictive amorphous wires about 100% change per Oe of mag-netic field was observed.
