GMI effect of amorphous microwires with enhanced magnetic softness

Journal of the Korean Physical Society, 2013
We present our results on studies of soft magnetic properties and GMI effect in thin microwires at elevated frequencies paying special attention to tailoring the GMI effect and achievement of high GMI ratio (ΔZ/Z), high magnetic field sensitivity (dZ/dH) with low hysteretic behavior.

Influence of alloy composition on GMI effect in amorphous ribbons

AIP Conference Proceedings, 2018
The paper presents the comparative study of Giant Magneto Impedance (GMI) effect in amorphous ribbons of different composition. In paper fundamental aspects of GMI effect, designed measuring stand and obtained results were described. Ribbons with dimension: 1 mm wide, 50 mm long, 22 µm thick in as-cast state, have been investigated with exciting ...

Frequency dependence of GMI effect in nanocrystalline Fe86Zr7B6Cu1 ribbons

Journal of Magnetism and Magnetic Materials, 1999
Abstract Giant magnetoimpedance effect (GMI), Δ Z / Z , has been studied in Fe 86 Zr 7 B 6 Cu 1 ribbons after heat treatment at 550°C and 600°C for 1 h (samples A and B respectively). Measurements were performed at frequencies, f , of the AC driving current ranging between 50 and 1400 kHz and under an axial magnetic field, H , up to 1440 A/m ...

Magnetization Process and GMI Effect in As-Cast Nanocrystalline Microwires

IEEE Transactions on Magnetics, 2010
Results on the axial and circumferential magnetization processes in as-cast nanocrystalline glass-coated microwires are reported for the first time. Glass removal induces a peculiar change in the shape of the axial hysteresis loop. The initially rectangular axial hysteresis loop becomes almost anhysteretic after glass removal as a consequence of a ...

Effect of Nanocrystallization on Magnetic Properties and GMI Effect of Microwires

IEEE Transactions on Magnetics, 2014
We studied giant magnetoimpedance (GMI) effect and magnetic properties of FINEMET-type FeCuNbSiB microwires. We observed that the GMI effect and magnetic softness of glass-coated microwires produced by the Taylor–Ulitovski technique can be tailored either controlling magnetoelastic anisotropy of as-prepared FeCuNbSiB microwires or controlling their ...

Practical Use of the GMI Effect to Make a Current Sensor

IEEE Transactions on Magnetics, 2019
This paper deals with practical issues and solutions related to the use of the giant magnetoimpedance (GMI) for electrical current measurement. It presents an overview of a full attempt of design and realization of an almost industrial GMI-based current sensor or clamp. The sensor combines dc and ac measurements with the same flexible sensitive element.

Magnetic Detector Based on GMI Effect of Amorphous Wire

Advanced Materials Research, 2012
The giant magneto-impedance (GMI) effect of amorphous wire and its affecting factors were analyzed. Magnetic impedance (MI) element was designed with a special structure. So the difficulties of complex negative feedback circuit and winding double circuits on amorphous wire were solved.

Magnetic Properties and GMI Effect of Ductile Amorphous Microwires

IEEE Transactions on Magnetics, 2012
We report on studies of the effect of annealing on magnetic properties and giant magneto-impedance (GMI) effect in Co69Fe4Cr4Si12B11 amorphous microwires with diameters of 90 and 55 μm produced by the Tailor-Ulitovski method allowing rapid quenching of composite glass coated microwires followed by glass removal techniques and warm drawing.

Effect of Nanocrystallization on Magnetic Properties and GMI Effect of Fe-rich Microwires

Journal of Electronic Materials, 2014
We studied the giant magnetoimpedance (GMI) effect and magnetic properties of Finemet-type FeCuNbSiB microwires. We observed that the GMI effect and magnetic softness of glass-coated microwires produced by the Taylor–Ulitovski technique can be tailored by controlling the magnetoelastic anisotropy of as-prepared FeCuNbSiB microwires, and can also be ...
