High Temperature Dielectric Anomaly of Ammonium Sulfate [(NH 4) 2SO 4] Crystal

概要

論文の詳細を見る
Dielectric anomalies were observed in ammonium sulfate [(NH4)2SO4] crystals at $T_{0}\simeq 413$ K after the crystal was heated above 413 K. Frequency dependence of dielectric loss across $T_{0}\simeq 413$ K observed in the 2nd heating-up cycle could be best fitted by two overlapping relaxation functions of the Cole-Cole type. The fast component in higher frequency region depicts a sharp discontinuity of relaxation frequency at $T_{0}\simeq 413$ K while the slow component in lower frequency region shows a continuous slowing down to zero relaxation frequency as temperature increased to $T_{0}\simeq 413$ K.
