There is an increasing need for high-permittivity (high-k) materials due to rapid development
of electrical/electronic industry. It is well-known that single composition materials cannot …

Relaxor ferroelectrics were discovered almost 50 years ago among the complex oxides with
perovskite structure. In recent years this field of research has experienced a revival of …

Feature size is a natural determinant of material properties. Its design offers the
technological perspectives for material improvement. Grain size, crystallite size, domain …

A model of relaxor ferroelectrics based on the interacting polar clusters picture has been
formulated. The electric dipole moment of a nanosized polar domain is allowed a large …

Relaxor ferroelectricity is one of the most widely investigated but the least understood
material classes in the condensed matter physics. This is largely due to the lack of …

Dielectric and Raman scattering experiments were performed on various ceramics with
composition Ba (Ti 1-x Zr x) O 3. Such lead-free, environmental-friendly materials were …

Substitutional charge disorder giving rise to quenched electric random-fields (RF s) is
probably at the origin of the peculiar behavior of relaxor ferroelectrics, which are primarily …

Dielectric permittivity ɛ as a function of temperature is measured in PbMg 1/3 Nb 2/3 O 3
and a number of other relaxor ferroelectrics with the perovskite structure. It is found that the …

A first-principles-based technique is developed to investigate the properties of Ba (Zr, Ti) O 3
relaxor ferroelectrics as a function of temperature. The use of this scheme provides answers …
