In-situ Overhauser-enhanced nuclear magnetic resonance at less than 1 μT using an atomic magnetometer.
Journal of Magnetic Resonance(2019)
摘要
•The first in-situ Overhauser-enhanced nuclear magnetic resonance experiment using an atomic magnetometer at ultra-low field.•Signal-to-noise ratio was 32 after sixteen averages.•On the Larmor precession of 1H spins, a decaying oscillation was superimposed.•We attribute it to a transient 87Rb spin precession in response to a non-adiabatic field variation.•Atomic magnetometry technique shows a new capability of zero and ultralow-field NMR.
