The accurate detection of very weak biomagnetic signals with a sensitivity of fT levels and
map** nanoscale magnetic field variations are two of the most significant challenges for …

This paper aims to review the technology, developments, and applications of spin exchange
relaxation free (SERF) atomic magnetometers. The generalized comparisons between the …

In this study, a wearable multichannel human magnetocardiogram (MCG) system based on
a spin exchange relaxation-free regime (SERF) magnetometer array is developed. The MCG …

Overcoming poor readout is an increasingly urgent challenge for devices based on solid-
state spin defects, particularly given their rapid adoption in quantum sensing, quantum …

Optically-pumped magnetometers constitute a valuable tool for imaging biological magnetic
signals without cryogenic cooling. Nowadays, numerous developments are being pursued …

More than 50 years ago superconducting quantum interference devices (SQUIDs) were
invented. Since then many applications opened up. Already in a 1980 workshop (Weinstock …

Optically pumped magnetometers are becoming a promising alternative to cryogenically-
cooled superconducting magnetometers for detecting and imaging biomagnetic fields …

We have constructed a low-cost, portable, high-sensitivity 16-channel optically pumped
magnetometer (OPM), operating in the spin-exchange relaxation-free regime, and …

Here we demonstrate an atomic magnetometer that has a bandwidth of more than 100 kHz
and a sensitivity of 180 fT/√ Hz at a Fourier frequency of 8 Hz, and 0.7 nT/√ Hz at 100 kHz …

In this paper, we present the first proof of concept confirming the possibility to record
magnetoencephalographic (MEG) signals with optically pumped magnetometers (OPMs) …
