Suppressing laser-power noise with a multifunctional liquid crystal polarization grating in miniaturized optically pumped magnetometers [PDF]

Microsystems & Nanoengineering
Optically pumped magnetometers (OPMs) enable high-resolution biomagnetic imaging, yet conventional single-beam designs are constrained by bulky, alignment-intensive polarization optics and susceptibility to laser-power noise.

Measurement of the Magnetic Field of the CDF Magnet [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1985
The magnetic field of the CDF (Collider Detector at Fermilab) superconducting solenoid has been measured using a newly designed field mapping device. NMR probes and a system of three orthogonal search coils were used as sensing elements. The central uniform region inside the solenoid coil and the fringing field in the conical end plugs were measured ...

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 ...

Measuring huge magnetic fields [PDF]

Nature, 2002
Huge magnetic fields are predicted to exist in the high-density region of plasmas produced during intense laser-matter interaction, near the critical-density surface where most laser absorption occurs, but until now these fields have never been measured.

Magnetic-Based Polydimethylsiloxane Microspheres for Magnetic Field Measurement [PDF]

IEEE Transactions on Instrumentation and Measurement, 2022
Magnetic-based polydimethylsiloxane microspheres (MPMs) are fabricated and its applications for measurement of magnetic field are investigated. The MPMs are prepared by first incorporating the uniformly sized Mn3O4 nanocrystals into polydimethylsiloxane (PDMS) matrix, and then using a self-assembling method to obtain a chain of microspheres on the ...

Precise Determination of Magnetic Gradient Relaxation of Coupled Atomic Spin Ensemble in Spin-Exchange Relaxation-Free Co-Magnetometer

Photonics, 2023
Inside a spin-exchange relaxation-free (SERF) co-magnetometer with a high-pressure buffer gas atomic cell, the magnetic field gradient causes the decoherence of atomic spins to produce magnetic-field gradient relaxation.
