Advances in Fluxgate Magnetometry for Space Physics

2017
Fluxgate magnetometers are an essential tool for solar-terrestrial research and monitoring or forecasting space weather. They provide high precision measurements of the Earth’s magnetic fields and can be used to infer the currents that transport energy and momentum through the magnetosphere and ionosphere.

Physics-informed neural networks for solving nonlinear Bloch equations in atomic magnetometry

Physica Scripta, 2023
In this study, we address the challenge of analyzing spatial spin distribution based on the nonlinear Bloch equations in atomic magnetometry through the use of physics-informed neural networks (PINNs).

Master-equation-based model for infrared-based magnetometry with nitrogen-vacancy-centers-in-diamond cavities: A path to subpicotesla sensitivity at submillimeter scales

Physical Review Applied
Our study aims to increase the spatial resolution of high-sensitivity magnetometry based on singlet-transition infrared (IR) absorption using nitrogen-vacancy (NV) centers in diamonds in monolithic cavities, with potential applications in bio-magnetic ...

Quantum diamond microscope with circularly polarized microwave excitation for wide-field vector magnetometry

Photonics Europe
We report a quantum diamond microscope for rapid, spatially resolved magnetic imaging across a wide-field of view. We use it to measure optically detected magnetic resonance spectra of randomly oriented single crystal nanodiamonds with dense NV ...

Stable π-Extended Thio[7]helicene-Based Diradical with Predominant Through-Space Spin-Spin Coupling.

Journal of the American Chemical Society
In this work, a novel π-extended thio[7]helicene scaffold was synthesized, where the α-position of the thiophene unit could be functionalized with bulky phenoxy radicals after considerable synthetic attempts.
