Precision Magnetic Field Sensing with Dual Multi-Wave Atom Interferometer

open access: yesSensors, 2022
Precision magnetic field measurement is widely used for practical applications, fundamental research, and medical purposes, etc. We propose a novel quantum magnetometer based on atoms’ multi-wave (3-wave and 5-wave) Ramsey interference.

Investigation of the Differences in Onset Times for Magnetically Conjugate Magnetometers

open access: yesFrontiers in Astronomy and Space Sciences, 2022
We have identified nearly 1,000 onsets using two pairs of hemispheric conjugate ground magnetometers where the onset is defined based on a sharp decline in the H component of the magnetic field at a ground magnetometer station.

Open-Source Magnetometer for Characterizing Magnetic Fields in Ultracold Experiments

open access: yesApplied Sciences, 2023
We demonstrate a fully automated open-source magnetometer designed primarily for characterization of magnetic fields produced by coils, permanent magnets or by parasitic sources. It is based on an Arduino Mega microcontroller and a three-axis Hall sensor

Evaluation of Self-Field Effects in Magnetometers Based on Meander-Shaped Arrays of Josephson Junctions or SQUIDs Connected in Series

open access: yesMicromachines, 2021
Arrays of superconducting quantum interference devices (SQUIDs) are highly sensitive magnetometers that can operate without a flux-locked loop, as opposed to single SQUID magnetometers. They have no source of ambiguity and benefit from a larger bandwidth.

Comparative analysis of microelectromechanical inertial measurement units of various manufacturers for human motor activity monitoring [PDF]

open access: yesОмский научный вестник, 2020
In this paper, we compare microelectromechanical inertial measuring modules that can be used to record the motor activity of a person. The comparison involved sensors with nine degrees of freedom of the lower price category.
