Abstract

It is widely known that the ferroelectric phase transition from tetragonal to cubic phase in BaTiO₃ ceramics and powders is strongly suppressed compared with the crystals. In our study the features of this transition were investigated by low-frequency Raman scattering and second harmonic generation (SHG) techniques. The obtained results of Raman and SHG experiments are interpreted as a relaxor-like behavior of BaTiO₃ pressed powder.
