Investigating the hyperfine systematic error and relative phase in low spin-polarization alkali FID magnetometers

D. P. Hewatt, M. Ellmeier, C. Kiehl +4

Alkali-metal optically-pumped magnetometers are prone to inaccuracies arising from the overlap of the average F = I + 1/2 and F = I - 1/2 ground-state Zeeman resonances. We employ…
