Peculiarities of dielectric properties of proton conducting (K$_{0.3}$(NH$_{4}$)$_{0.7}$)$_3$H(SO$_4$)$_2$ single crystals (to discussion of negative dielectric permittivity)

On the example of superprotonic crystal (K$_{0.3}$(NH$_{4}$)$_{0.7}$)$_3$H(SO$_4$)$_2$, a first attempt was made to detect, by means of dielectric investigations, the presence of structure elements in the material, which are devoid of elastic bonds or having loosen bonds with crystal matrix. It was shown that it is possible to separate contributions from structure elements with elastic bonds, which are devoid of elastic bonds or having loosen bonds in comparison with influence of measuring field. A supposition was stated about sequence of physical mechanisms which determine the reaction of quasi-free structure elements on the growth of measuring field.
