Abstract

We present a continuous-wave (cw) analogue of the spin-echo, nuclear magnetic resonance (NMR) method for measuring self-diffusion, The possibility of using this method for measuring self-diffusion in solid “super-ionic conductors” is discussed. The essential feature of this new method involves supplementing the usual homogeneous magnetic field modulation in a cw NMR experiment with a magnetic-field-gradient (MFG) with modulation frequency (ωG/2π) larger than the resonant line width (expressed in frequency units). Line widths of the observed center-band and side-bands as a function of peak MFG, then depend upon the self-diffusion constant of the nucleus under investigation in a simple way.
