In conclusion, I believe it fair to say that the marriage of ultrasonics and magnetic resonance holds promise of being a productive one. In the application of these disciplines to nuclear spins, little more has been done than to demonstrate the acoustic techniques and to apply them to a particular problem of quadrupolar coupling in the heavy alkali halides. Particularly promising is the extension of acoustic NMR techniques to bulk metals, to ferromagnetic crystals, and to the study of spin-lattice relaxation as a function of temperature. In the technique of phonon coupling to electron spins in paramagnetic materials, also, the reports to date have all been of a preliminary nature. Used in combination with the powerful new hypersonic technique of generating microwave acoustic waves, electron spin-phonon interaction measurements may help to resolve some of the present confusion regarding the mechanisms of spin-lattice relaxation in paramagnetic solids (29).

“…Such two-quantum (⌬m I ϭ2)-single photon transitions, which should be contrasted to the n-quantum-n-photon transition usually observed in pulsed NMR spectroscopy, 16,17 have been observed in conventional NMR in the context of overtone spectroscopy, 18 by acoustic resonance, 19,20 by electric resonance, 21 and in low-field NMR. [22][23][24] In the case of low-field NMR, the transitions observed are so-called flipflip transitions, where two ͑or more͒ spins flip simultaneously.…”

Coupling mechanisms for optically induced NMR in GaAs quantum wells

et al. 2002

Optical pumping can increase the polarization of nuclear spins in semiconductors such as GaAs by many orders of magnitude, improving the sensitivity in conventionally detected nuclear magnetic resonance ͑NMR͒ experiments. Optical detection of these NMR transitions provides an additional increase in sensitivity, and furthermore, can distinguish signal contributions from different quantum wells in multiple quantum well samples. In this article we study the coupling mechanisms for all-optical NMR experiments, where modulation of the cw optical excitation at the nuclear Larmor frequency induces transitions between the nuclear spin states. We find clear evidence for two different types of interaction between the photogenerated carriers and the nuclear spins: the hyperfine interaction and the coupling between the electric field of the electron and the nuclear quadrupole moment. While the former induces only ⌬m I ϭϮ1 transitions, the latter also causes ͑single photon-͒ ⌬m I ϭϮ2 transitions.
