Abstract: The size effect of the dielectric properties and the barrier height was investigated in the ferroelectric solid solution Ba x Sr 1−x TiO 3 system. The decrease of the grain size causes the suppression of the ferroelectricity, and the increase of the relaxation frequency. Barrier heights increase with increasing grain size. The result is analogous to magnetic phase transitions in nanocrystals and other solid-solid phase transitions in nanocrystals. It suggests a general rule that may be of use in the discovery of new metastable phases. An explanation of this phenomenon was given by an electric potential model that agrees well with the experimental results. For Ba x Sr 1−x TiO 3 system, the decrease of x causes the decrease of the barrier height. Copyright Società Italiana di Fisica, Springer-Verlag 1999
