摘要：
The macroscopic and microscopic magnetic properties for amorphous and nanocrystalline Fe73.5CU1Nb3Si3.5B9 powder have been investigated and their giant magneto-impedance (GMI) effect is reported for the first time. The experimental results show that powder sample annealed at 510degreesC possesses the optimum soft magnetic properties. However, the maximum longitudinally driven GMI (LDGMI) ratio (about 52%) is found in the sample annealed at 600degreesC. This means that the LDGMI ratio depends on not only their magnetic properties but also their electric properties.
