Fluxgate Offset Study
(IEEE, 2014)
Offset and its long-term stability is a weak point of fluxgate sensors. Even the ultrastable sensors kept at no vibrations and stable temperature at magnetic observatories show offset drift. Such drift of the fluxgate ...
Influence of Magnetostriction of NiFe Electroplated Film on the Noise of Fluxgate
(IEEE, 2014)
We electroplated NiFe thin-film over a copper layer using different current density. Magnetostriction is changed from negative to positive values, with minimum magnetostriction found at around Fe19Ni81 composition. When ...
Electroplated FeNi ring cores for fluxgates with field induced radial anisotropy
(American Institute of Physics, 2015)
Being able to control the anisotropy of a magnetic core plays an important role in the development of a fluxgate sensor. Our aim is to induce anisotropy orthogonal to the direction of excitation because it generates a ...
Noise dependence on temperature in fluxgates with electroplated core
(Elsevier Science, 2016)
Samples of electrodeposited fluxgate sensors with varying magnetostriction coefficient were manufactured and their noise was studied at various temperatures. We show that the noise of the fluxgate is, under some conditions, ...
Effect of Electroplated Ni1-xFex Composition on the Field-Induced Anisotropy
(IEEE, 2016)
Field-induced anisotropy has been proposed as an effective method to produce ferromagnetic rings with radial anisotropy for fluxgate cores. Compared with stress-induced anisotropy, this method easily allows generating a ...
Magnetostriction Offset of Fluxgate Sensors
(IEEE, 2015)
Magnetostriction Offset of Fluxgate Sensors: we examined the origoins of offset both theoretically an experimentally
Effect of Stress Induced Anisotropy on the Noise of Ring-core Fluxgate
(IEEE, 2015)
In this paper we show how an anisotropy perpendicular to the direction of excitation is favourable to obtain low noise in fluxgate sensors. We produced ring cores by electroplating NiFe thin film (6 μm) over a bended copper ...
Sensitivity and noise of parallel fluxgate sensor with amorphous wire cores
(Elsevier, 2022)
Fluxgate sensors are vectorial magnetic field sensors suitable for the measurement of fields up to mT with maximum pT resolution. Due to their low weight, low power, and low cost, fluxgates are ideal sensors to monitor the ...
