Influence of Molecular Electric Fields on Elastic Properties of Perovskite-Like Substrates

Abstract

The dynamics of ΑΒCO4 deformable crystals with electroelastic interacting was expressed by theoretical model with wave-linear approximation.The one-dimensional problem was considered assuming that the field variables are represented by plane electroelastic waves. As a result the dispersion equation for these crystals was obtained. Using this model the data concerning the elastic properties of SrLaGaO4 are discussed.

IR-spectroscopic behaviour of AA′BO4 oxides belonging to the K2NiF4 structural type

“…Taking into account that a number of the new ceramic high T c superconductors are also related to the mentioned structural type [3][4][5][6], compounds adopting this structure appear as specially promising candidates as substrate materials. In fact, some of them have already been assayed for this purpose with good success [7][8][9][10][11][12][13][14].…”
