Nuclear quantum-assisted magnetometer [PDF]
Review of Scientific Instruments, 2017 Magnetic sensing and imaging instruments are important tools in biological and material sciences. There is an increasing demand for attaining higher sensitivity and spatial resolution, with implementations using a single qubit offering potential improvements in both directions.

L’application de la géophysique marine au diagnostic subaquatique
Archéopages, 2015 The size of the areas that need to be surveyed underwater can quickly get out of hand, which means that traditional survey methods of total survey of the seabed by divers are not up appropriate.

Near Real-Time Estimation of Geomagnetic Local K Index From Gyeongzu Magnetometer [PDF]
Journal of Astronomy and Space Sciences, 2005 Local K-index is an indicator representing local geomagnetic activity in every 3 hour. For estimation of the local K-index, a reasonable determination of solar quiet curve (undisturbed daily variation of geomagnetic field) is quiet essential.

Detection of radio frequency magnetic fields using nonlinear magneto-optical rotation [PDF]
, 2006 We describe a room-temperature alkali-metal atomic magnetometer for detection of small, high frequency magnetic fields. The magnetometer operates by detecting optical rotation due to the precession of an aligned ground state in the presence of a small ...

Diamond magnetometer enhanced by ferrite flux concentrators [PDF]
Physical Review Research, 2019 Magnetometers based on nitrogen-vacancy (NV) centers in diamond are promising room-temperature, solid-state sensors. However, their reported sensitivity to magnetic fields at low frequencies (≾1 kHz) is presently ≿10 pT s1/2, precluding potential ...

Real-space imaging of non-collinear antiferromagnetic order with a single-spin magnetometer [PDF]
Nature, 2017 Although ferromagnets have many applications, their large magnetization and the resulting energy cost for switching magnetic moments bring into question their suitability for reliable low-power spintronic devices.

A Portable Magnetometer for Magnetic Measurements of Meter‐Sized Meteorites
Geochemistry, Geophysics, Geosystems, 2020 Meteorites contain records of past magnetic fields in the form of natural remanent magnetization (NRM). A key property of meteorite magnetization that provides information about its origin is its dependence on spatial scale.
