Abstract
The recent development of network analyzers has allowed electromagneti c property studies in perovskite-type ferroelectric materials in a lar ge frequency range (similar to 10(2)-10(10)Hz). A high frequency (simi lar to 10(7)-10(10)Hz) relaxation has been evidenced. The origin of th e relaxation process has been determined: it is an intrinsic mechanism directly related to the crystal lattice. In the light of the obtained results, physical-chemistry laws can be used to modulate the relaxati on frequency using appropriate ionic substitutions.
