“…Although we saw in section 3 that reducing the number of atoms worsens the sensitivity of a magnetometer, there may be strong motivations for miniaturization-including reduced standoff distance and improved spatial resolution, or integration of the cell into small quantum systems [23,96,111,[113][114][115][149][150][151] with low size, weight, and power (SWaP). Production of MEMS ('micro-electromechanical systems') vapor cells for magnetometers and atomic clocks is a rapidly growing field, typically incorporating anodic-bonding techniques [152][153][154].…”

This article is designed as a step-by-step guide to optically pumped magnetometers based on alkali atomic vapor cells. We begin with a general introduction to atomic magneto-optical response, as well as expected magnetometer performance merits and how they are affected by main sources of noise. This is followed by a brief comparison of different magnetometer realizations and an overview of current research, with the aim of helping readers to identify the most suitable magnetometer type for specific applications. Next, we discuss some practical considerations for experimental implementations, using the case of an M z magnetometer as an example of the design process. Finally, an interactive workbook with real magnetometer data is provided to illustrate magnetometer-performance analysis.

“…The ground-state Hanle effect is a well-known physical phenomenon produced by the resonant excitation of an atomic medium with a polarized light beam in the presence of a scanning magnetic field [1][2][3][4][5][6]. This effect is typically observed in a degenerate two-level atomic system (i.e.…”

We present experimental and theoretical investigations of the dependence of double Hanle resonance spectrum on the light polarization angle and the direction of the applied transverse magnetic field (TMF). The experiments are done for F g = 2 → F e = 1 transition of 87Rb D1 line using a rubidium vapor cell containing buffer gas. We show that a small light polarization component along the direction of TMF introduces asymmetry in the double Hanle resonance signal. Both the magnitude and sign of asymmetry in the signal are sensitive to the TMF orientation, suggesting a possible method for in-situ measurement of the direction of the magnetic fields generated by the coils. The physical origin of this asymmetry is explained by considering the redistribution of population among the ground-state Zeeman sublevels in the presence of TMF. In addition, we systematically vary both the polarization angle and TMF direction to study their effect on the line profile of Hanle resonances. We demonstrate that a double Hanle resonance changes to a dark Hanle resonance by rotating the light polarization vector irrespective of the TMF direction. We have developed a simple theoretical model based on a degenerate two-level system to explain our experimental observations.
