Enhanced giant magnetoimpedance in heterogeneous nanobrush [PDF]
Nanoscale Research Letters, 2012 Abstract A highly sensitive and large working range giant magnetoimpedance (GMI) effect is found in the novel nanostructure: nanobrush. The nanostructure is composed of a soft magnetic nanofilm and a nanowire array, respectively fabricated by RF magnetron sputtering and electrochemical deposition.

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

Tailoring of Magnetic Softness and Magnetoimpedance of Co‐Rich Microwires by Stress Annealing
physica status solidi (a), Volume 218, Issue 12, June 2021., 2021 Stress annealing allows avoiding magnetic hardening and remarkably improving the magnetic softness and giant magnetoimpedance ratio of Co‐rich microwires. Properly stress‐annealed Co‐rich microwires present almost unhysteretic loops with coercivity about 2 A m−1 and magnetic anisotropy field about 35 A m−1.

Frequency and Magnetic Field Dependence of the Skin Depth in Co-rich Soft Magnetic Microwires
Advanced Electromagnetics, 2016 We studied giant magnetoimpedance (GMI) effect in magnetically soft amorphous Co-rich microwires in the extended frequency range. From obtained experimentally dependences of GMI ratio on magnetic field and different frequencies we estimated the ...

Tailoring of magnetic softness and GMI effect in Fe-rich thin magnetic wires
AIP Advances, 2018 We present comparative studies of magnetic properties and giant magnetoimpedance (GMI) effect of Fe and Co-rich microwires. As-prepared Co-rich microwires present much higher GMI ratio.
