Measurement of magnetic noise in magnetoimpedance sensing element

EPJ Web of Conferences, 2018
A method for measurement of magnetic noise in magnetoimpedance sensing element is proposed. Glass-coated Co-based amorphous microwires with a slightly negative magnetostriction were used as the sensing element.

Magnetoimpedance Effect on Single NiFe Nanowire

Journal of Superconductivity and Novel Magnetism, 2017
In this study, Ni82Fe18 nanowires were deposited on Au-coated porous anodic alumina oxide (AAO) template by electrochemically. Scanning electron microscopy showed that wires have diameters of about 250–310 nm and length of 50–60 μm. NiFe nanowire arrays embedded in AAO were mechanically polished until nanowires appeared. Later, electrical contacts were

Tunable asymmetric magnetoimpedance effect in ferromagnetic NiFe/Cu/Co films [PDF]

, 2014
We investigate the magnetization dynamics through the magnetoimpedance effect in ferromagnetic NiFe/Cu/Co films. We observe that the magnetoimpedance response is dependent on the thickness of the non-magnetic Cu spacer material.

Wearable Magnetic Field Sensor with Low Detection Limit and Wide Operation Range for Electronic Skin Applications. [PDF]

Adv Sci (Weinh)
A flexible magnetic sensor with low detection limit and wide measuring range is reported, realized by the anisotropy of the giant magneto‐impedance effect of amorphous wire. The sensor can detect the magnetic field from 22 nT to 400 mT, and simultaneously monitor weak magnetic fields such as geomagnetism and large magnetic fields which come from ...

Spin Hall magnetoimpedance [PDF]

Physical Review B, 2014
The recently discovered spin Hall magnetoresistance effect electrically probes pure spin current flow across a ferrimagnetic insulator/normal metal bilayer interface. While usually the DC electrical resistance of the bilayer is measured as a function of the magnetization orientation in the magnetic insulator, we here present magnetoimpedance ...

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 ...

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.

Magneto-X Effects in Magnetic Soft Materials and Their Applications. [PDF]

Adv Sci (Weinh)
This review systematically explores magnetic soft materials (MSMs), a novel class of composites that transform under magnetic fields. It catalogs fundamental “Magneto‐X” effects, classifies materials by their matrix and magnetic fillers, and highlights transformative applications in soft robotics, biomedical devices, flexible electronics, etc. Finally,
