High Sensitivity Optically Pumped Quantum Magnetometer
The Scientific World Journal, Volume 2013, Issue 1, 2013., 2013 Quantum magnetometers based on optical pumping can achieve sensitivity as high as what SQUID‐based devices can attain. In this paper, we discuss the principle of operation and the optimal design of an optically pumped quantum magnetometer. The ultimate intrinsic sensitivity is calculated showing that optimal performance of the magnetometer is attained ...

Ultrawide Bandwidth Optomechanical Magnetometry Using Flux Concentration
Advanced Functional Materials, Volume 36, Issue 65, 13 August 2026.High‐permeability flux concentrators enable ultrawide‐bandwidth chip‐scale optomechanical magnetometry by exploiting magnetic nonlinearity to up‐convert low‐frequency fields to the mechanical resonance, where sensitivity is optimal. This enables flat wideband operation over more than four orders of magnitude, from tens of kilohertz to sub‐hertz ...
