Description
Summary:New leadless ferroelectric relaxor ... ceramics have been obtained. The ceramics exhibits a smeared frequency-dependent maximum of permittivity, which follows the Fogel-Vulcher law with the freezing temperature T... = 250 K. The Last mode in 0.85...-0.15... ceramics is the ferroelectric soft mode inside polar nanoregions, with the critical temperature T... = 437 K. (ProQuest: ... denotes formulae/symbols omitted.)
