Exploring the temperature dependence of magnetic properties and magnetoimpedance effect in Co-rich microwires

Journal of Science: Advanced Materials and Devices
We studied the temperature dependence of the magnetic properties and giant magnetoimpedance, GMI, effect in as-prepared and annealed Co69.2Fe3.6Ni1B12.5Si11Mo1.5C1.2 glass-coated microwires with nearly-zero magnetostriction.

Integration of thin film giant magnetoimpedance sensor and surface acoustic wave transponder

, 2012
Passive and remote sensing technology has many potential applications in implantable devices, automation, or structural monitoring. In this paper, a tri-layer thin film giant magnetoimpedance (GMI) sensor with the maximum sensitivity of 16%/Oe and GMI ...

Low-cost Sensors Based on the GMI Effect in Recycled Transformer Cores

Sensors, 2008
Sensors based on the giant magnetoimpedance (GMI) effect in silicon steelswere constructed. Strips of silicon steels (0.500 mm-thick, 35.0 mm-long) with widthsranging from 0.122 to 1.064 mm were cut from recycled transformer cores.

Giant Magnetoimpedance Effect In Soft Magnetic Wires For Sensor Applications

, 2015
The giant magneto-impedance effect (GMI) consists of the large relative change of the impedance (up to around 300%) observed in magnetically very soft ribbon and wire alloys under the application of dc magnetic fields (units of kA m-1). The phenomenology

Rotational giant magnetoimpedance in soft magnetic wires: Modelization through Fourier harmonic contribution [PDF]

, 2015
A method to investigate the giant magnetoimpedance effect based on Fourier analysis is introduced. The study is carried out on a FeCoSiB amorphous wire with vanishing magnetostriction subjected to joule heating (current annealing) treatment that induces ...

Tuning of magnetic properties and giant magnetoimpedance effect in multilayered microwires

Journal of Science: Advanced Materials and Devices
We studied the magnetic properties and Giant Magnetoimpedance (GMI) effect in amorphous Co-rich microwires with similar chemical compositions and different diameters with magnetic (Co, Permalloy) and non-magnetic (Cu) layers deposited by magnetic ...

Resonance enhancement of the giant magnetoimpedance effect in glass-coated microwires with outer conductive layer

, 2007
We investigated resonance enhancement of the giant magnetoimpedance effect in Fe-based glass-coated microwires with an outer copper layer. We found that a capacitance forms between the ferromagnetic core and the outer conductive layer, where the glass ...

Phenomenological theory of the giant magnetoimpedance of composite wires

, 2013
Composite wires with a three-layered structure are known to show a particularly large magnetoimpedance effect. The wires consist of a highly conductive core, an insulating layer and an outer ferromagnetic shell.

Magnetic Properties and Applications of Glass-coated Ferromagnetic Microwires

Advanced Electromagnetics, 2023
A remarkable magnetic softness and giant magnetoimpedance (GMI) effect at GHz frequency range havebeen observed in glass-coated microwires subjected to appropriate postprocessing. Co-based microwires present higher GMI effect.
