Nonlinear Magnetoimpedance Effect in FeCoNi Ferromagnetic Tubes [PDF]
Chinese Physics Letters, 2001 [EN] The very high (up to 820% of the magnetoimpedance ratio) and sensitive nonlinear giant magnetoimpedance effect has been studied in the FeCoNi magnetic tubes electroplated onto Cu(3%)Be nonmagnetic wire for frequencies from 1-10 MHz. Special annealing was carried out in order to induce the magnetic anisotropy.

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 ...

Estimating the Net Magnetic Moment of Geological Samples From Planar Field Maps Using Multipoles
Geochemistry, Geophysics, Geosystems, Volume 24, Issue 7, July 2023., 2023 Abstract Recent advances in magnetic microscopy have enabled studies of geological samples whose weak and spatially nonuniform magnetizations were previously inaccessible to standard magnetometry techniques. A quantity of central importance is the net magnetic moment, which reflects the mean direction and the intensity of the magnetization states of ...

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.

Electronics and Communications in Japan, Volume 104, Issue 2, June 2021., 2021 Abstract We have suggested the current‐induced magnetic modulation spectroscopy (CIMMS) to detect human cardiopulmonary activity in sediment for lifesaving. Initially, a Finite Element (FE) model of human in sediment was developed to simulate impedance change by human cardiopulmonary activity and an optimal electrode arrangement was estimated to detect
