High sensitive magnetic sensor with amorphous wire

2015 9th International Conference on Sensing Technology (ICST), 2015
Using a FeCoSiB amorphous wire and a coil wrapped around it, we developed a sensitive magnetic sensor. To improve the linearity of the field response, a feedback method was used. When a 5 mm long amorphous wire with the diameter of 0.1 mm was used, the magnetic field noise of the sensor was about 30 pT per root Hz above 30 Hz.

Domain collapse in amorphous magnetostrictive wires

1992. Digests of Intermag. International Magnetics Conference, 1992
In magnetostrictive amorphous wires of composition (Fe/sub 77.5/Si/sub 7.5/B/sub 15/) the process of domain collapse is an important ingredient of reentrant reversal. During collapse, a narrow and high voltage pulse is generated due to the formation of an unstable domain.

Circumferential permeability in nonmagnetostrictive amorphous wires

Journal of Materials Research, 1996
Real and imaginary components of the impedance response on Co68.1Fe4.4B15Si12.5 amorphous as-cast wires were measured in the 100 Hz-100 kHz frequency range and 0.05–30 mA (RMS) current amplitude, at axial dc fields of 0 and 4800 A/m. From these data, plots of circumferential complex permeability as a function of circular field, as well as magnetization

Torsion impedance of CoFeSiB amorphous wires

Journal of Magnetism and Magnetic Materials, 2002
Abstract In this work we report some results concerning the torsion impedance of amorphous Co 68.1 Fe 4.4 Si 12.5 B 15 wires in the as-cast state, and after a stress annealing treatment. The influence of the drive current amplitude and frequency is also studied for these samples. A sensitivity to the applied torsion up to 17.6%/rad m is obtained for

Magnetostrictive influence on the bistability of amorphous wires

Journal of Applied Physics, 1990
We have studied the effect of tension and external field on the magnetization process in amorphous positive magnetostrictive Fe-Si-B wires. The radial stress created during the in-rotating water quenching technique of producing these wires causes a radial anisotropy.

Ferromagnetic resonance in submicron amorphous wires

Journal of Applied Physics, 2012
Ferromagnetic resonance in glass-coated amorphous wires with the diameter of metallic core varying from 25 μm to 133 nm is investigated. The microwave frequencies of 49.1 and 69.7 GHz are used and static magnetic field is applied either parallel or perpendicular to the long wire axis.

Calculation of residual stresses in amorphous wires

Glass Physics and Chemistry, 2000
The residual internal stresses in a cylindrical wire produced in the rotating-water melt spinning process and a coated wire obtained by drawing from a melt have been calculated within the thermal viscoelasticity and structural relaxation theories. The coated wire consists of the core and the sheath with different thermal properties.

Mechanism of asymmetrical magnetoimpedance in amorphous wires

Journal of Applied Physics, 1999
Two approaches for obtaining asymmetrical magnetoimpedance (MI) characteristics in Co-based negative magnetostrictive amorphous wires are analyzed in terms of the surface impedance tensor ζ̂, which is expressed in the form of orthogonal expansions in Bessel functions in a general case of a helical magnetization.

Joule heating in amorphous metallic wires

Journal of Physics D: Applied Physics, 1995
Non-conventional heating treatments, such as Joule heating, can produce materials with attractive physical properties. Although extensively explored in amorphous wires and ribbons, one of the major drawbacks of the technique is the intrinsic difficulty in determining the annealing temperature.
