Advances in SQUID magnetometers [PDF]
IEEE Transactions on Electron Devices, 1980 The operation and noise limitations of de and RF SQUID's are outlined, and recent advances in their sensitivity are discussed. A model of the dc SQUID predicts an energy noise level per hertz referred to the SQUID of approximately 8 k_{B}TL/R \approx 8 k_{B}T(\piLC)^{1/2} , where L, R, and C are the SQUID inductance and the shunt resistance and ...

Magnetometers for tracking metallic targets [PDF]
2010 13th International Conference on Information Fusion, 2010 Starting from Maxwell's equations, we derive a sensor model for three-axis magnetometers suitable for localization and tracking applications. The model depends on the relative position between the sensor and the target, and a physical magnetic multipole model of the target.

NMR Detection with an Atomic Magnetometer [PDF]
Physical Review Letters, 2005 We demonstrate detection of NMR signals using a non-cryogenic atomic magnetometer and describe several novel applications of this technique. A water free induction decay (FID) signal in a 0.5 $μ$T field is detected using a spin-exchange-relaxation-free K magnetometer and the possibility of using a multi-channel magnetometer for 3-D MRI requiring only a

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.
