Back Cover: A Novel Co-Magnetometer Based on Double-Probe in Situ Decoupling of Magnetic Field and Inertia Rotation (Adv. Quantum Technol. 8/2025)

Abstract

In article number 2500253, Wenfeng Fan, Wei Quan, and co-workers report a novel in-situ magnetic noise compensation mechanism in a K-Rb-21Ne atomic comagnetometer, leveraging differential spin polarization of two alkali metals. This system decouples magnetic fields and inertial rotations in situ, enabling simultaneous measurement of both parameters and enhancing stability for precision spin-interaction studies.
