Cavity Optomechanical Magnetometer [PDF]
Physical Review Letters, 2012 A cavity optomechanical magnetometer is demonstrated where the magnetic field induced expansion of a magnetostrictive material is transduced onto the physical structure of a highly compliant optical microresonator. The resulting motion is read out optically with ultra-high sensitivity.

Magnetometer-Detected Nuclear Magnetic Resonance of Photochemically Hyperpolarized Molecules
, 2023 Photochemically induced dynamic nuclear polarization (photo-CIDNP) enables nuclear spin ordering by irradiating samples with light. Polarized spins are conventionally detected via high-field chemical-shift-resolved NMR (above 0.1 T).

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.

Electrodynamics of an omega-band as deduced from optical and magnetometer data [PDF]
, 2009 We investigate an omega-band event that took place above northern Scandinavia around 02:00–02:30 UT on 9 March 1999. In our analysis we use ground based magnetometer, optical and riometer measurements together with satellite based optical images.

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.
