Abstract:

During the first and second quarters of the present contract, an initial literature survey of all known tungsten-bronze compounds was completed. Preliminary formulation of the Gibbs energy function for ferroic materials to describe the phase transitions has been accomplished. Apparatus to perform LPE growth of tungsten-bronzes has been constructed and several suitable flux systems for the growth of strontium-barium-niobate SBN films have been found. From an analysis of the chemistry of SBN, several new compounds have been identified and may be readily obtained by element substitutions within the SBN structure.
