Zjawiska dyspersyjne i przewodnictwo elektryczne w relaksorach, multiferroikach i strukturach wielowarstwowych.

Abstract

The phenomenon of ferroelectricity was discovered less than 100 years ago and a rapid increase in the group of ferroelectrics has been discernible since the 1950s. Among them, an important place is occupied by ferroelectrics with perovskite structure and their solid solutions. A group of materials that is very close to ferroelectrics are the so-called relaxors and relaxor ferroelectrics, which are characterized by exceptional application properties. Multiferroics and multilayer structures are another group of materials with specific application qualities; in these materials, the phenomenon of ferroelectricity plays an important role. For application reasons (lower cost), these materials are often produced in the ceramic form. The subject matter of the present monograph is the aforementioned group of materials, i.e. relaxors, multiferroics, and multilayer structures in the ceramic form. The work attempts to systematize and complete the knowledge of these materials, including the phenomena (effects) occurring in them. Moreover, it provides a review of literaturę published on this subject over many years.
