Basic Studies of a Fluorine Anion Superionic Conductor.
Abstract
Audio frequency conductivity and capacitance measurements in the temperature range of 5.4-310K have been used to study the conductivity and dipolar relaxation phenomena in calcium doped lanthanum trifluoride. Measurements have been taken at five frequencies from 100 Hz to 10 kHz on samples varying in concentration from 0.01% to 0.3% one strong dipolar dielectric relaxation and several weaker relaxations have been observed both parallel and perpendicular to the c-axis. The strong dipolar relaxation has been attributed to the realignment of a charge compensating fluorine ion vacancy about a substitutional alkaline-earth ion. The weaker relaxations have been attributed to trace impurities because of the lack of any regular progression in either concentration or direction of applied field. (Author)
