Giant Magnetoimpedance in CoP Electrodeposited Films

Key Engineering Materials, 2014
In the last few years there has been increasing interest in CoP electrodeposited alloys due to their excellent properties as soft magnetic materials (low coercivity and high permeability) in addition to the giant magnetoimpedance that they exhibit. More recently magneto-impedance (MI) effect has also been reported on thin films obtained by sputtering ...

Giant magnetoimpedance in CoP electrodeposited microtubes

Journal of Materials Research, 2000
Co90P10 amorphous microtubes with thickness ranging from 2 to 19 μm were electrodeposited onto Cu wire substrates. Samples exhibit radial magnetic anisotropy as deduced from hysteresis loops and magnetic force microscopy imaging. These microtubes show quite noticeable giant magnetoimpedance effect (GMI) with amplitude depending on layer thickness and ...

A position sensor based on magnetoimpedance

Journal of Applied Physics, 1996
A magnetic-field sensor based on the giant magnetoimpedance phenomenon is presented. It is shown that a low, negative magnetostriction CoFeBSi amorphous wire can be used to detect the presence or passage of moving pieces or vehicles, simply by pasting a small permanent magnet on the vehicles/pieces.

Giant magnetoimpedance effect in Fe wires

Materials Science and Engineering: B, 2001
In the present work we report, for the first time, the giant magnetoimpedance effect in pure Fe wire with grain size of tens micrometers. The impedance as well as resistance and reactance decrease with application of d.c.

Micromachined layered thin film magnetoimpedance element

INTERMAG Asia 2005. Digests of the IEEE International Magnetics Conference, 2005., 2005
This paper presents a micromachined layered magnetoimpedance (MI) element consisting of a CoNbZr/Al/CoNbZr film and its MI properties were investigated. Sensitivity defined as maximum fractional change in impedance changed with thickness and dimension.

Magnetoimpedance biosensor prototype for ferrogel detection

Journal of Magnetism and Magnetic Materials, 2017
Abstract Ferrogels are composite materials widely introduced in the area of biomedical engineering as magnetic field sensitive transformers. These biomimetic materials can be prepared by incorporating monodomain magnetic nanoparticles into chemically crosslinked hydrogels.

Advances in Giant Magnetoimpedance of Materials

2015
Abstract The giant magnetoimpedance (GMI) effect consisting of the large change of both real and imaginary parts of the impedance upon the application of static magnetic field has attracted recent few years' considerable attention. An updated review on GMI was presented.

Giant Magnetoimpedance Sensors and Their Applications

2016
Since GMI changes as a function of external dc magnetic field or applied dc/ac current, it is possible to design and produce GMI-based sensors that can measure either magnetic fields or dc/ac currents. GMI also changes sensitively with applied stress, and this provides a new opportunity to develop stress sensors.

Microwave Magnetoimpedance of Superconducting Tin

Physical Review, 1964
Measurements, using a bimodal cavity, of the temperature and magnetic field dependence of the surface impedance of a single crystal of superconducting tin at a frequency of 23.5 Gc/sec are reported. In the geometry used, the static and microwave magnetic fields were parallel over the surface of the sample. The temperature dependence of the reactance in
