Nuclear magnetic resonance detection of the nuclear spins near paramagnetic impurities in solids Academic Article uri icon

abstract

  • It was shown that on applying two radio-frequency fields, both of the same amplitude, one rotating at the frequency ω I for nuclei inside the diffusion barrier and one rotating at the frequency ω S for nuclei outside the diffusion barrier, the Hartmann-Hahn condition will be reached, which results in conservation of Zeeman energy in the spin-diffusion process and destruction of the spin-diffusion barrier. This technique can be used to detect the nuclear magnetic resonance signal from the nuclei located near paramagnetic impurities.
