Unshielded portable optically pumped magnetometer for the remote detection of conductive objects using eddy current measurements. [PDF]
Review of Scientific Instruments, 2022 Electrically conductive objects can be detected using the principle of electromagnetic induction, where a primary oscillating magnetic field induces eddy currents in the object, which in turn produce a secondary magnetic field that can be measured with a

The Europa Clipper Magnetometer
Space Science Reviews, 2023 Global-scale properties of Europa’s putative ocean, including its depth, thickness, and conductivity, can be established from measurements of the magnetic field on multiple close flybys of the moon at different phases of the synodic and orbital periods ...

Theoretical advantages of a triaxial optically pumped magnetometer magnetoencephalography system
NeuroImage, 2021 The optically pumped magnetometer (OPM) is a viable means to detect magnetic fields generated by human brain activity. Compared to conventional detectors (superconducting quantum interference devices) OPMs are small, lightweight, flexible, and operate ...

Three-axis closed-loop optically pumped magnetometer operated in the SERF regime.
Optics Express, 2022 We propose a three-axis closed-loop optically pumped magnetometer with high sensitivity. The closed-loop magnetometer has a three-axis sensitivity of approximately 30 fT/Hz1/2 using two orthogonal laser beams for pumping and probing the alkali metal ...
