Integration of the SERF Magnetometer and the Mz Magnetometer Using Micro-Fabricated Alkali Vapor Cell

With the continuous improvement of weak magnetic detection technology, there has been a growing trend towards more compact and integrated magnetometer. The SERF magnetometer and the Mz magnetometer have many common features in operation. Therefore, we design a new kind of miniaturized atomic sensors to integrate the SERF magnetometer and the Mz magnetometer based on micro-fabricated alkali vapor cell. The sensor structure consists of alkali vapor cell, three-axis magnetic field coils, heating module and optical module. This small size sensor has the potential to achieve a portable multi-function device.
