Giant Magnetoimpedance in Electrodeposited Cobalt on Silver Wires

Walailak Journal of Science and Technology, 2011
Cobalt of thickness from 1 to 25 mm was coated onto 120 mm-diameter silver wires by electrodeposition. Giant magneto-impedance (GMI) of electrodeposited cobalt on silver wires was measured with ac current from 1 kHz to 1 MHz.

Giant magnetoimpedance effect and spin accumulation in conjugated polymeric networks with inhomogeneity

AIP Advances
The magnetoimpedance effect allows us to estimate the extent of spin dependent scattering in disordered solids. The change in impedance with respect to applied magnetic field manifests through local change in permeability on the surface and it amplifies ...

Off-Diagonal Magnetoimpedance in Annealed Amorphous Microwires with Positive Magnetostriction: Effect of External Stresses

Magnetism, 2023
It was observed recently that the giant magnetoimpedance (GMI) effect in Fe-rich glass-coated amorphous microwires with positive magnetostriction can be improved significantly by means of post-annealing.

Perspectives in Giant Magnetoimpedance Magnetometry [PDF]

Sensor Letters, 2009
Approximate expressions are obtained for the sensitivity of a GMI wire. The optimal conditions for high sensitivity are discussed in terms of material and external parameters, such as dc field, dc current bias, driving current amplitude and frequency. We show that the systematic reduction of the anisotropy field is not necessarily the best approach to ...

Reversible and Non-Reversible Transformation of Magnetic Structure in Amorphous Microwires

Nanomaterials, 2020
We provide an overview of the tools directed to reversible and irreversible transformations of the magnetic structure of glass-covered microwires. The irreversible tools are the selection of the chemical composition, geometric ratio, and the stress ...

Magnetic Functionalization of Poly(N‐isopropylacrylamide) Hydrogels for Sensor Applications

physica status solidi (b), Volume 259, Issue 8, August 2022., 2022
Herein, methods of introducing large quantities of magnetic nanoparticles into Laponite‐based PNIPAM hydrogels are investigated. Particles are coated with 3‐(trimethoxysilyl)propyl methacrylate and integrated using a magnetic field during the hydrogel synthesis to create large rod‐like agglomerations.
