Sensitive detection of magnetic field is one of the open problem inmetrology. Here, we propose an Mach-Zehnder atomic interferometry tosensitively detect the very weak local magnetic field, which is expelled by thesuperconductor (as the "testing magnet") due to the Meissner effect. Theinduced magnetic field gradient near the superconductor provides a centripetalacceleration of the atomic motion in the interferometry and thus can bedetected by using the atomic interferences. Given gravity acceleration of theatoms have been measured at the accuracy of $10^{-12}$ g, the measuredsensitivity of the expelled local field could reach $10^{-14}$ T.

Sensitive detection of local magnetic field changes with atomic interferometry by using superconducting Meissner effects
