English Abstract
The Sr2−xK1+xNb5O15−xFx (0⩽x⩽1) solid solution of tetragonal tungsten bronze (TTB)-type was characterized by both crystallographic and dielectric properties. For small values of x (0⩽x<0.20), the ferroelectric-paraelectric ...Read more >
The Sr2−xK1+xNb5O15−xFx (0⩽x⩽1) solid solution of tetragonal tungsten bronze (TTB)-type was characterized by both crystallographic and dielectric properties. For small values of x (0⩽x<0.20), the ferroelectric-paraelectric transition is in good agreement with the long-range spontaneous polarization and the polar space group of the low temperature phase. For highest values of x (0.20⩽x⩽1), the ionic disorder resulting from coupled...Read less <
