Background:

Magnetoencephalography (MEG) requires sensitive magnetometers to detect weak neuronal magnetic fields.
Existing compact atomic magnetometers (AMs) often use Potassium (K) or Rubidium (Rb) with single-beam configurations.
There is a need for compact, highly sensitive AMs suitable for multi-channel MEG arrays.

Purpose of the Study:

To introduce a novel Cesium-based AM (Cs-AM) with a pump-probe two-beam configuration for detecting human neuronal magnetic fields.
To demonstrate the advantages of the Cs-AM, including operation in the spin-exchange relaxation free (SERF) regime and enhanced sensitivity.
To evaluate the performance of the Cs-AM for magnetoencephalography (MEG) recordings.

Main Methods:

Developed a compact Cs-AM utilizing a 4 mm vapor cell and a pump-probe two-beam configuration.
Operated the Cs-AM in the SERF regime, enabling lower heating temperatures and reduced noise.
Measured human auditory evoked fields (AEFs) using the Cs-AM and compared results with a commercial superconducting quantum interference device (SQUID).

Main Results:

The Cs-AM achieved a noise level of approximately 10 fT/Hz^1/2 in the 10 Hz to 30 Hz frequency band, comparable to state-of-the-art AMs.
Observed a clear M100 peak in AEFs with a significantly larger amplitude using the Cs-AM compared to SQUID channels.
Demonstrated good agreement in temporal profiles between the Cs-AM and SQUID measurements.

Conclusions:

The developed compact Cs-AM is suitable for magnetoencephalography (MEG) recordings.
The two-beam configuration and SERF operation provide higher sensitivity and reduced interference.
The Cs-AM has strong potential for integration into multi-sensor arrays and gradiometers for future neuroscience research.
