Effect of Stress Induced Anisotropy on the Noise of Ring-core Fluxgate
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 ...
Fluxgate Offset Study
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
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 ...
Field Annealed Closed-path Fluxgate Sensors Made of Metallic-glass Ribbons
(Elsevier Science, 2012)
One-step field annealing of Co-based metallic glass was chosen to acquire low-magnetostrictive material with anisotropy required to reduce noise by favoring magnetization rotation. Despite the risk of bending stress ...
Effect of Electroplated Ni1-xFex Composition on the Field-Induced Anisotropy
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 ...
Effects of Core Dimensions and Manufacturing Procedure on Fluxgate Noise
(Polish Academy of Sciences, 2014)
The effect of demagnetizing factor and manufacturing procedure on noise of the fluxgate probes, manufactured from metallic glasses, is presented. The fluxgate probes were either tape-wound, or flat, wet-etched ringcore ...
