AI Overview
The best atomic magnetometers with the highest sensitivity are Spin Exchange Relaxation Free (SERF) magnetometers, often developed by researchers at Princeton University, which achieve femtotesla-level (
T) sensitivity. These are superior for applications like MEG, while commercial options like the CIQTEK SpinMag-I offer high performance in portable forms.
Key Considerations
- Sensitivity: While SERF provides the highest sensitivities (< 1 fT), they operate best in shielded environments with very low magnetic fields.
- Applications: These sensors are ideal for biomagnetism (brain/heart imaging), geological prospecting, and fundamental physics.
- Alternatives: TMR (Tunneling Magnetoresistance) sensors like the ALT021 offer high sensitivity and a smaller form factor but are generally not considered true "atomic" magnetometers.
