  • Title: All-optical magnetometry for NMR detection in a micro-Tesla field and unshielded environment.
    Author: Bevilacqua G, Biancalana V, Dancheva Y, Moi L.
    Journal: J Magn Reson; 2009 Dec; 201(2):222-9. PubMed ID: 19828344.
    Abstract:
    An all-optical atomic magnetometer is used to detect a proton free-precession signal from a water sample polarized in a 0.7 T field and remotely analyzed in a 4 microT field. Nuclear spins are manipulated either by pi/2 pulses or by non-adiabatic rotation. The magnetometer operates at room temperature, in an unshielded environment and has a dual-channel sensor for differential measurements.
