Abstract
The superionic phase transition in a single-domain crystal of (NH4)(3)H(SeO 4)(2) is studied by means of Electron Spin Resonance using VO2+ A discontin uous narrowing of the linewidth is observed at its superionic transition po int. This phenomenon can be regarded as a motional narrowing that originate s in the dynamic fluctuation of the pyramidal SeO4 tetrahedron which brings about superionic conductivity.
