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 ...
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 ...
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 ...
Identification of geomagnetic pulsations in SQUID data for Space Weather research
(IEEE, 2024)
The SQUID records small geomagnetic variations such as pulsations, which are short period fluctuations of the geomagnetic field at ULF frequencies. To distinguish pulsations from uncorrelated noise, the SQUID data is ...
1-pT noise fluxgate magnetometer for geomagnetic measurements and unshielded magnetocardiography
(IEEE, 2020)
We present the development of a low-noise, fundamental-mode, orthogonal fluxgate magnetometer with four amorphous, annealed ferromagnetic wires. The 1-Hz noise obtained in open-loop and closed-loop is as low as 0.75 and ...
