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.

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

Magnetoimpedance and Stressimpedance effect at FeSiB Wires

Erzincan Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2021
In this study, the magnetoimpedance (MI) and stress impedance (SI) effect properties of Fe77.5Si7.5B15 wires have been investigated. Wires were annealed at 460 oC for different times. The largest change in the MI was observed at 1MHz ac current frequency value.

Magnetoimpedance effects in a CoNiFe nanowire array

Journal of Alloys and Compounds, 2013
Abstract This report describes the growth of CoNiFe nanowires into highly ordered porous anodic alumina oxide (AAO) templates by DC electrodeposition at a pH value of 2.6. Scanning electron microscopy (SEM) observations revealed that the wires have diameters of approximately 270–290 nm and a length of 25 μm. The energy dispersive X-ray (EDX) analysis

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.

Magneto-Impedance Biosensor Sensitivity: Effect and Enhancement

Sensors, 2020
Biosensors based on magneto-impedance (MI) effect are powerful tools for biomedical applications as they are highly sensitive, stable, exhibit fast response, small in size, and have low hysteresis and power consumption.

3D Self‐Assembled Microelectronic Devices: Concepts, Materials, Applications

Advanced Materials, Volume 32, Issue 15, April 16, 2020., 2020
Conventional microelectronics have difficulties accommodating a number of 3D electronic components. Self‐assembled 3D architectures are gradually brought into the field of microelectronics realizing 3D self‐assembled passive, active, sensory, mechanical and energy‐supply devices.
