A New Method for Reduction of Atomic Magnetometer Noise Based on Multigene Genetic Programming
IEEE Access, 2019 An ultra-high precision magnetic field measurement is of great scientific and economic significance. An atomic magnetometer that operates in a spin-exchange relaxation-free (SERF) regime has superior sensitivity and, thus, is of great significance for ...

Repumping atomic media for an enhanced sensitivity atomic magnetometer
Optics Express, 2022 Atomic vapour magnetometers sense the local magnetic field strength by measuring the resulting precession rate of a well-defined quantum state. An essential prerequisite for this approach is a requirement to drive the media into this quantum state, which is frequently achieved via optical pumping.

Multi-sensor magnetoencephalography with atomic magnetometers [PDF]
Physics in Medicine and Biology, 2013 The authors have detected magnetic fields from the human brain with two independent, simultaneously operating rubidium spin-exchange-relaxation-free magnetometers. Evoked responses from auditory stimulation were recorded from multiple subjects with two multi-channel magnetometers located on opposite sides of the head.

Analysis and Correction of the Crosstalk Effect in a Three-Axis SERF Atomic Magnetometer
Photonics, 2022 Three-axis atomic magnetometers have an excellent advantage for determining the complete vector information of a magnetic field to be measured. However, the crosstalk effect, which leads to an error output on one axis owing to a magnetic field on the ...

Benchtop Magnetic Shielding for Benchmarking Atomic Magnetometers
IEEE Transactions on Instrumentation and Measurement, 2023 Here, a benchtop hybrid magnetic shield containing four mumetal cylinders and nine internal flexible printed circuit boards is designed, constructed, tested, and operated. The shield is designed specifically as a test-bed for building and operating ultra-sensitive quantum magnetometers. The geometry and spacing of the mumetal cylinders are optimized to

All-Optical Parametric-Resonance Magnetometer Based on 4He Atomic Alignment
Sensors, 2022 Parametric-resonance magnetometer is a high-sensitivity quantum sensor characterized by applying the non-resonant radio-frequency (RF) fields to the atomic ensemble. The RF fields lead to crosstalk in the multi-sensor design, thus disturbing the magnetic-
