Phase transitionsand ferroelectrics: revival and the future in the field

Phase Transitionsand recent advances in liquid-crystals research

“…In a very recent editorial, Kreisel et al [1] have given a brief overview of the important topics covered by the papers that appeared in Phase Transitions, among which are two categories, namely, functional oxides and liquid crystals (LCs). Kreisel et al discuss functional oxides, whereas the present editorial reviews discuss the recent developments in the field of LCs.…”

Recent Advances in Processing, Structural and Dielectric Properties of PMN-PT Ferroelectric Ceramics at Compositions Around the MPB

“…Although several authors have reported the existence of the M B phase for the PMN-PT system, this phase has not yet been effectively observed. The revision of results and traditional notions acquired about ferroelectrics in the past few decades has led to new ideas and interpretations, demanding new experiments and models to explain the nature of the MPB (Kreisel et al, 2009;Khachaturyan, 2010). Some partial conclusions indicate that the MPB is considered more of a region than a boundary, characterized by two competing coexisting phases.…”

Strain analysis of multiferroic BiFeO3-CoFe2O4 nanostructures by Raman scattering

“…[1][2][3] To overcome the scarcity of single-phase multiferroics, and to provide new magnetoelectric coupling mechanism at room temperature, recent work concentrates on the class of artificial multiferroics in the form of composite-type materials or thin film nano-/hetero-structures. [4][5][6][7][8] In such systems, it is the elastic coupling interaction between the magnetostrictive phase and the piezoelectric phase that leads to the observed magnetoelectric response.…”
