Abstract
These transitions have been detected by differential scanning calorimetry, impedance and modulus spectroscopy techniques. The first transition at T=39 5 K is related to NH,(+)(4) reorientation and H+ diffusion. The conductivit y relaxation parameters associated with some K+/NH4+: and H+ conduction hav e been determined from an analysis of the M"/M" max spectra measured in a w ide temperature range. Transport properties in this material appear to be d ue to an K+ /NH4+: and H+ ions hopping mechanism. (C) 1999 Elsevier Science B.V. All rights reserved.
