Gamma Irradiation Effect on Asymmetric Giant Magnetoimpedance of Co68.15Fe4.35Si12.5B15 Amorphous Alloy

The giant magneto impedance (GMI) effect is a large variation in the electrical impedance of a magnetic conductor when subjected to a static magnetic field. The sensitivity to the direction (AGMI) and magnitude of applied  magnetic field    and also linearity levels   of this  effect are three important parameters in magnetic sensors application. A suitable annealing procedure can be used to ac...

High-temperature giant magnetoimpedance in Fe-based nanocrystalline alloy

Giant magnetoimpedance ~GMI! was investigated from room temperature up to 823 K in an Fe-based nanocrystalline Fe73.0Cu1.0Nb2.5V1.0Si13.5B9.0 ribbon. With an increment of the measuring temperature ~T!, GMI shows notable enhancement followed by a declining dependence, yielding a maximum value around 603 K where the relative GMI is nearly four times that at room temperature. The field at the peak...

Longitudinally driven giant magnetoimpedance effect in stress-annealed Fe-based nanocrystalline ribbons

A high-frequency longitudinally driven giant magnetoimpedance ~GMI! effect has been measured in stress-annealed Fe73Cu1Nb1.5V2Si13.5B9 nanocrystalline ribbons. Based on how the impedance phase varies with the external magnetic field, it becomes clear that the imaginary part of the complex permeability, m9, which is related to magnetic losses, plays an important role in the high-frequency longit...
