Abstract

By analyzing the relative frequencies and amplitude of multiple electromagnetically induced transparency resonances in external magnetic field, we achieve scalar magnetometer sensitivity <5pT/Hz, and can determine the B-field direction with angular sensitivity < 1° using machine learning and optical lock techniques in a 100 mm3 atomic vapor cell.
