    • A Portable Ultrasensitive SERF Atomic Magnetometer for Biomagnetic Measurements 

      Proite, Nicholas; Cook, Peter; Li, Zhimin; Wakai, Ronald T.; Walker, Thad G.; Wyllie, Robert (2009-09-10)
      We present a portable Rb cell atomic magnetometer suited for biomagnetic measurements. Working in the spin-exchange relaxation free regime, we demonstrate an initial white noise floor of 60 fT$/\sqrt {Hz} $. We show an ...

    • Ultrasensitive Atomic Magnetometers 

      Wyllie, Robert; Wakai, Ronald T.; Walker, Thad G. (2009-09-10)
      We have developed a novel, small-volume portable single-channel atomic biomagnetometer and have used it to detect adult MCG signals. The cryogenic-free magnetometer has sufficiently high sensitivity (20 fT/rt(Hz)) that ...
