Bias-Field-Free Operation of Nitrogen-Vacancy Ensembles in Diamond for Accurate Vector Magnetometry
PRX QuantumAccurate measurement of vector magnetic fields is critical for applications including navigation, geoscience, and space exploration. Nitrogen-vacancy (NV) center spin ensembles offer a promising solution for high-sensitivity vector magnetometry, as their

Maximum-variance gradiometer technique for removal of spacecraft-generated disturbances from magnetic field data [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2020 In situ measurement of the magnetic field using spaceborne instruments requires a magnetically clean platform and/or a very long boom for accommodating magnetometer sensors at a large distance from the spacecraft body.

Multiscale estimation of the field-aligned current density [PDF]
Annales Geophysicae, 2019 Field-aligned currents (FACs) in the magnetosphere–ionosphere (M–I) system exhibit a range of spatial and temporal scales that are linked to key dynamic coupling processes. To disentangle the scale dependence in magnetic field signatures of auroral FACs

Iridium Communications Satellite Constellation Data for Study of Earth's Magnetic Field
Geochemistry, Geophysics, Geosystems, 2021 Characterization of Earth's magnetic field is key to understanding dynamics of the core. We assess whether Iridium Communications magnetometer data can be used for this purpose since.

The Psyche Magnetometry Investigation
Space Science Reviews, 2023 The objective of the Psyche Magnetometry Investigation is to test the hypothesis that asteroid (16) Psyche formed from the core of a differentiated planetesimal. To address this, the Psyche Magnetometer will measure the magnetic field around the asteroid

The universal shear conductivity of Fermi liquids and spinon Fermi surface states and its detection via spin qubit noise magnetometry [PDF]
New Journal of Physics, 2021 We demonstrate a remarkable property of metallic Fermi liquids: the transverse conductivity assumes a universal value in the quasi-static (ω → 0) limit for wavevectors q in the regime lmfp−1≪q≪pF , where l mfp is the mean free path and p F is the Fermi ...

Sensitivity optimization for NV-diamond magnetometry [PDF]
, 2019 Solid-state spin systems including nitrogen-vacancy (NV) centers in diamond constitute an increasingly favored quantum sensing platform. However, present NV ensemble devices exhibit sensitivities orders of magnitude away from theoretical limits.
