A pulsed-field-gradient nuclear magnetic resonance spectrometer was successfully constructed, which is based on a superconducting magnet and has magic-angle spinning capabilities. A dewar facility is an integral part of this system so as to permit investigation of ionic diffusion down to 77 K, along with a sample heating arrangement for diffusion measurements up to 300 C. This spectrometer has been employed in the measurements of protonic diffusion coefficients in beta-alumina solid electrolytes and cation, anion, and self-diffusion coefficients and amorphous polymeric electrolytes.
