Savukov develops SERF and RF atomic magnetometers for ultra-low-field NMR/MRI, MEG, and electromagnetic induction imaging, pushing pT/fT-level detection in unshielded and low-field regimes. This vapour-phase approach reaches femto-to-picotesla sensitivities complementary to NV-center diamond ensemble quantum sensors (DEER, nano-NMR, T1 relaxometry) that operate near the pT/sqrt(Hz) regime.
