Magnetoimpedance effect in a NiFeMoMn supermalloy ribbon

Materials Science and Engineering: B, 2000
Abstract The magnetoimpedance (MI) effect in NiFeMoMn supermalloy ribbon, as well as the magnetoresistance and magnetoreactance, are investigated as the functions of the dc magnetic field and ac driving current frequency. The longitudinal MI reaches 44% in 65 Oe at 0.2 MHz but the transverse effect is small (

Giant magnetoimpedance effect enhanced by thermoplastic drawing

Journal of Applied Physics, 2014
We performed thermoplastic forming (TPF) on FeCoNbB metallic glass ribbons with a supercooled liquid region exceeding 100 K, and found the sample after TPF is still completely amorphous. More importantly, the giant magnetoimpedance (GMI) effect was improved after the forming process: the maximum GMI ratio and sensitivity increased from 41% to 12.3%/Oe ...

Magnetoimpedance effect in Co-rich metallic glasses

Journal of Magnetism and Magnetic Materials, 2003
Abstract Some aspects of the magnetoimpedance (MI) effect in amorphous ribbons and wires are analysed. In concrete, the explanation of the phenomenon based on the frequency and the driving current amplitude dependencies is given. Also, the different MI responses depending on the external parameters that play an importat role in this effect, such as ...

Giant magnetoimpedance effect enhancement by circuit matching

Sensors and Actuators A: Physical, 2003
GMI response of amorphous wires can be greatly increased by working at resonant conditions in a LC cell. This feature of the circuit can be exploited to increase the sensibility of current GMI-based sensors while selecting the working frequency.

Magnetic sensor based on giant magnetoimpedance effect

2008 8th International Symposium on Antennas, Propagation and EM Theory, 2008
A giant magnetoimpedance (GMI) magnetic sensor is designed in the present work. Differing from the previously reported sensors, a couple of permanent magnets are applied to provide a bias magnetic field for the sensor probe which consists of commercial amorphous ribbon.

Magnetoimpedance effect in FINEMET/Ni80Fe20 composite ribbons

Journal of Alloys and Compounds, 2018
Abstract Giant magnetoimpedance (GMI) always attracts much attention owing to its importance in promising applications of industrial devices. Although GMI effect of ribbons have been studied for years, the composite ribbons coated with various films are still attractive due to its high sensitivity with respect to the applied magnetic field.

Study of microwave magnetoimpedance effect in amorphous FeSiB wires

Journal of Magnetism and Magnetic Materials, 2007
Abstract Measurements of microwave magnetoimpedance of melt-extracted Fe-rich amorphous wires are presented. These wires were simultaneously submitted to a microwave electromagnetic wave propagating at the wire surface, Joule heating and circumferential static magnetic field.

Effect of nanocrystallization on Giant magnetoimpedance effect of microwires

2013 Seventh International Conference on Sensing Technology (ICST), 2013
We studied GMI effect and magnetic properties of Finemet-type FeCuNbSiB microwires. We observed that GMI magnetic field and frequency dependences and magnetic softness of composite microwires produced by the Taylor-Ulitovski technique can be tailored either controlling magnetoelastic anisotropy of as-prepared FeCuNbSiB microwires or controlling their ...
