An automated and versatile ultra-low temperature SQUID magnetometer [PDF]
, 2004 We present the design and construction of a SQUID-based magnetometer for operation down to temperatures T = 10 mK, while retaining the compatibility with the sample holders typically used in commercial SQUID magnetometers.

Characterizing atomic magnetic gradiometers for fetal magnetocardiography
Review of Scientific Instruments, 2019 Atomic magnetometers (AMs) offer many advantages over superconducting quantum interference devices due to, among other things, having comparable sensitivity while not requiring cryogenics. One of the major limitations of AMs is the challenge of configuring them as gradiometers.

Helicopter trial of magnetic tensor gradiometer [PDF]
ASEG Extended Abstracts, 2007 A SQUID (Superconducting Quantum Intereference Device) rotating tensor gradiometer has been test flown in a helicopter-towed bird over a magnetic dipolar source. The bird was instrumented with fluxgates, tiltmeters, a gyroscope and GPS receivers to assist in levelling and positioning.

Maximum-variance gradiometer technique for removal of spacecraft-generated disturbances from magnetic field data [PDF]
Geoscientific Instrumentation, Methods and Data Systems, 2020 In situ measurement of the magnetic field using spaceborne instruments requires a magnetically clean platform and/or a very long boom for accommodating magnetometer sensors at a large distance from the spacecraft body.

Development of precise off-diagonal magnetoimpedance gradiometer for magnetocardiography
AIP Advances, 2017 We have developed a precise off-diagonal magnetoimpedance (MI) gradiometer that can operate in an unshielded environment and at room temperature with 200 pT root-mean-square noise in a 100 Hz bandwidth.

Moving Wearable Magnetoencephalography Measurement Study Based on Optically-pumped Magnetometer
Chinese Journal of Magnetic Resonance, 2022 Magnetoencephalography is a non-invasive technology for brain function imaging, which is of enormous value to brain science research and clinical application due to its ultra-high temporal and spatial trace resolution.

Important design considerations for inboard airborne magnetic gradiometers [PDF]
GEOPHYSICS, 1984 The advantages of magnetic gradiometry as an adjunct to total field mapping are generally recognized and a few aircraft have been equipped with gradiometers. These gradiometers are derived from high‐sensitivity total‐field magnetometer systems that are in themselves subject to certain errors that can usually be tolerated in conventional surveys ...
