| dc.description.abstract | Dielectric permittivity measurements of ε′a and ε''a in a K0.60(NH4)0.40H2AsO4 mixed crystal have been made in the temperature and frequency ranges 3–300 K and 1 Hz–30 kHz. We find proton-glass behavior in this material similar to that observed in the Rb1−x(NH4)xH2AsO4 and Rb1−x(NH4)xH2PO4 systems. Below Tg the dielectric dispersion characteristics of the freezing of the polarization are well described phenomenologically by the Vogel-Fulcher law. The best fit gives the Vogel-Fulcher temperature T0=5.4 K, the attempt frequency ν0=2.5×1013 Hz, and the activation energy Ec/k=409 K. | en_US |
