# SERF + OTS coating
# SERF + 200 Torr Ne + 30 Torr N2
# Mx with paraffin coating
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 smaller self-spin-destruction rate than the magnetometers with buffer gas.
