A new spin-exchange relaxation-free (SERF) atomic magnetometer achieves unprecedented 0.54 fT Hz(-1/2) sensitivity in a compact 0.3 cm3 volume. This breakthrough promises non-cryogenic, high-resolution brain imaging and magnetic field detection.

Area of Science:

  • Physics
  • Biophysics
  • Quantum sensing

Background:

  • Superconducting quantum interference devices (SQUIDs) have dominated ultrahigh-sensitivity magnetic field detection for 30 years, enabling applications like magnetoencephalography.
  • Atomic magnetometers offer potential but struggle with sensitivity in compact designs needed for imaging.
  • Non-cryogenic, high-sensitivity atomic magnetometers are crucial for advanced applications like non-invasive brain mapping.

Purpose of the Study:

  • To develop a novel atomic magnetometer with enhanced sensitivity and spatial resolution.
  • To overcome the limitations of existing magnetic field detection technologies for biomedical applications.
  • To explore the potential of compact, high-performance magnetometers for brain activity mapping.

Main Methods:
