摘要
By analyzing the relative frequencies and amplitude of multiple electromagnetically induced transparency resonances in external magnetic field, we achieve scalar magnetometer sensitivity $ < 5{\text{pT}}/\sqrt {{\text{Hz}}} $, and can determine the B-field direction with angular sensitivity < 1° using machine learning and optical lock techniques in a 100 mm
