Optical detection of NMR J-spectra at zero magnetic field
M. P. Ledbetter, C. W. Crawford, A. Pines +4
Scalar couplings of the form J I_1 \cdot I_2 between nuclei impart valuable information about molecular structure to nuclear magnetic-resonance spectra. Here we demonstrate direct…
Cancellation of nonlinear Zeeman shifts with light shifts
K. Jensen, V. M. Acosta, J. M. Higbie +3
Nonlinear Zeeman (NLZ) shifts arising from magnetic-field mixing of the two hyperfine ground-states in alkali atoms lead to splitting of magnetic-resonance lines. This is a major s…
Detection of radio frequency magnetic fields using nonlinear magneto-optical rotation
M. P. Ledbetter, V. M. Acosta, S. M. Rochester +3
We describe a room-temperature alkali-metal atomic magnetometer for detection of small, high frequency magnetic fields. The magnetometer operates by detecting optical rotation due…
Magnetometry with millimeter-scale anti-relaxation-coated alkali-metal vapor cells
M. V. Balabas, D. Budker, J. Kitching +2
Dynamic nonlinear magneto-optical-rotation signals with frequency- and amplitude-modulated laser light have been observed and investigated with a spherical glass cell of 3-mm diame…
Hyperpolarized xenon nuclear spins detected by optical atomic magnetometry
V. V. Yashchuk, J. Granwehr, D. F. Kimball +5
We report the use of an atomic magnetometer based on nonlinear magneto-optical rotation with frequency modulated light (FM NMOR) to detect nuclear magnetization of xenon gas. The m…
