Magnetoimpedance effect in Fe flakes

Journal of Magnetism and Magnetic Materials, 2002
Abstract In the present paper the magnetoimpedance (MI) effect in Fe flakes is reported. The ratios of MI (Z(0)−Z(0.8 kOe ))/Z(0) , magnetoresistance (R(0)−R(0.8 kOe ))/R(0) and magnetoreactance (X(0)−X(0.8 kOe ))/X(0) almost intersect at a frequency of about 4 MHz, where the (Z(0)−Z(0.8 kOe ))/Z(0) reaches its ...

Giant magnetoimpedance effect in Fe wires

Materials Science and Engineering: B, 2001
In the present work we report, for the first time, the giant magnetoimpedance effect in pure Fe wire with grain size of tens micrometers. The impedance as well as resistance and reactance decrease with application of d.c.

Magnetoimpedance effect in FeCoMoSiB amorphous sheets

Technical Physics, 2003
The magnetoimpedance effect in sheets made of Fe4Co67Mo1.5Si16.5B11 amorphous metallic alloy is studied in relation to the mutual orientations of the sheet axis, permanent magnetic field, and variable electrical current. Also, the effective permeability is studied as a function of the mutual orientations of the sheet axis, permanent magnetic field, and

Magnetoimpedance effect in Nd3Fe77B20 amorphous ribbon

Journal of Magnetism and Magnetic Materials, 2002
Abstract In the present work, the magnetoimpedance (MI) effect in Nd 3 Fe 77 B 20 amorphous ribbon is reported. Such MI may be connected with the change of the permeability under fields. Nd–Fe–B ribbons with low Nd content not only have hard magnetic behaviors after nanocrystallization, but also show the large MI effect in as-cast amorphous state.

Magnetoimpedance effect in nanocrystalline FeZrNbB ribbons

Journal of Magnetism and Magnetic Materials, 2003
Abstract Magnetoimpedance (MI) effect has been investigated in stress annealed nanocrystalline FeZrNbB ribbons with slightly negative magnetostriction constants. The results indicate that annealing conditions, induced anisotropy and saturation magnetostriction are critical factors to the behaviour of MI effect.

Giant magnetoimpedance effect in sandwiched films

Journal of Applied Physics, 1999
The giant magnetoimpedance (GMI) effect in films with a sandwiched structure has been studied. FeNiCrSiB/Cu/FeNiCrSiB sandwiched films with a magnetic closed-loop structure were deposited onto a glass substrate by rf sputtering and then annealed at an optimum temperature.

Giant magnetoimpedance effect in Fe79.5P12C6Mo0.5Cu0.5Si1.5 nanocrystalline ribbons

Materials Science and Engineering: B, 2001
Abstract Nanocrystalline structure was observed in Fe 79.5 P 12 C 6 Mo 0.5 Cu 0.5 Si 1.5 ribbons after annealed at temperatures from 350 to 500°C. After annealed at 350°C, the ribbon Fe 79.5 P 12 C 6 Mo 0.5 Cu 0.5 Si 1.5 consists of nanoparticles bcc α-Fe(Si, C) and amorphous matrix.

The magnetoimpedance effect in rapidly solidified soft magnetic fibers

Journal of Magnetism and Magnetic Materials, 1996
Abstract Soft magnetic fibers, 20 to 50 μm in diameter, have been cast by melt extraction. A giant magnetoimpedance effect (GMI) of about 60% was observed in a (NiCo) 70 FeSiBMn fiber driven by a rf current. The magnetic field and frequency responses of fibers depend on the density and the frequency of the drive current.

Magnetoimpedance effect in amorphous and nanocrystalline ribbons

Journal of Applied Physics, 2001
The magnetoimpedance effect in several Co-rich amorphous ribbons is overviewed. Results are classified in the following sections: influence of anisotropies induced by stress annealing, dependence on applied stress, its dependence on stress or stress-impedance, and the appearance of hysteresis.

Magnetoimpedance effect in electroplated NiFeRu/Cu wire

Journal of Physics D: Applied Physics, 2006
Magnetoimpedance (MI) and hysteresis loops were studied in electroplated Ni79.1Fe20.9/Cu, Ni75.64Fe24.26Ru0.10/Cu, Ni79.51Fe20.31Ru0.18/Cu and Ni75.99Fe23.66Ru0.34/Cu wires. Scanning electron micrographs showed that crack-free electroplated wires were obtained with a smooth surface. The average grain size varied between 3 and 10 µm for all samples.
