Near constant loss regime in fast ionic conductors analyzed by impedance and NMR spectroscopies

Popis výsledku v původním jazyce

Universal dielectric response and nearly constant loss dispersive regimes have been investigated in fast ion conductors with perovskite and NASICON structure by using NMR and impedance spectroscopy. In perovskite compounds, local motions produced insideunit cells are responsible for the large "near constant loss" regime detected at low temperatures, however, in the case of NASICON compounds, local motions not participating in long-range charge transport were not detected. In both analyzed systems long-range correlated motions are responsible for dc-conductivity values of ceramics grains near 10 -3 S cm -1 at room temperature, indicating that low-temperature local motions, are not required to achieve the highest ionic conductivities.
