TLDR
In this article, the first experimental data of the temperature dependence of e′c and e″c for Rb1−x (NH4)x H2AsO4 was presented.Abstract:
We have presented the first experimental data of the temperature dependence of e′c and e″c for Rb1−x (NH4)x H2AsO4. The results are demonstrated by the presence of a glassy state in Rb1−x (NH4)x H2AsO4 for x = 0.31.read more
