# SERF + OTS coating (0.1 fT/sqrtHz)
# SERF + 300 Torr N2 (0.5 fT/sqrtHz)
# MxSynchronously pumped magnetometer with a paraffin coatingcoated cell (1.5 fT/sqrtHz)
 
Mx magnetometers don't achieve high sensitivity because they have lower alkali vapor concentration (can't heat coating above 60°C), and radiation trapping (no N2 in the cells). The SERF with OTS coating has narrower zero-field resonance line, so the probe can be detuned much closer than in the magnetometers with buffer gas. They also run at lower temperatures and so they have larger T1 due to decreased self-spin destruction collisions rate.
