Description
We report on the progress of implementing an atomic magnetometer based on free spin precession using our in-house manufactured rubidium-87 MEMS (micro-electromechanical systems) vapor cells. The magnetometer employs a pulsed pump and probe laser scheme, featuring a double pass through the vapor cell configuration for the probe laser beam. The magnetometer currently exhibits a sensitivity of 300$\,$fT/Hz${}^{1/2}$ with a bandwidth of 500$\,$Hz. The high dynamic range of the device, which ranges up to magnetic field strengths in the Earth's field regime, allows for a wide range of applications, e.g. the detection of biomagnetic signals from the human body, specifically signals stemming from cardiac activity. Finally, we will discuss the potential for a compact design in future iterations.
