Available in PDF, EPUB and Kindle. Book excerpt: Rhombohedral (R), monoclinic (MA/MC) and tetragonal (T) phases are found in coexistence in a compositionally segregated xPb(In1/2Nb1/2)O3- yPb(Mg1/3Nb2/3)O3- zPbTiO3 (PIN-PMN-PT) (nominal composition x/y/z = 30/35/35) single crystal. Polarized light (PLM) measurements and X-ray diffraction (XRD) on both single crystal and ceramic series confirms the existence of 2 different monoclinic phases. A phase diagram in the MPB region of the PIN-PMN-PT solid solution is proposed based on both single crystals and ceramic material.Further study on the temperature driven rhombohedral (R) (R3m)  monoclinic (MA) phase transition in the single crystals and ceramics with MPB composition are carried out. It was found that the rhombohedral domain is able to return to its original state after annealed at above the RMA phase transition temperature (TR-M) but below the Currie temperature (TC). A polarization reversal model is proposed based on the polarization rotation theory.Solid solutions of (1-x)Pb(Mg1/2W1/2)O3-xPb(M1/2W1/2)O3(M = Zn2+ and Mn2+) have been prepared by solid state reaction with composition x up to 30% for Zn and 50% for Mn. The influence of Zn2+ and Mn2+ on structure, electrical and magnetic properties are revealed. (1-x)PbZrO3-xPb(Mn1/2W1/2)O3 (x = 0 - 0.1) as another new solid solution system was also prepared by the solid state reaction method. Its crystal structure, dielectric properties and antiferroelectricity were investigated and it was proven to be an excellent candidate for energy storage devices.In summary, the study for PIN-PMN-PT ternary solid solution near its MPB composition shall provide a general guideline for designing high performance peizocrystals. The study of PZ-based and PMW-based antiferroelectric solid solutions provided better understanding of antiferroelectric perovskites and provides a different approach for the design of soft antiferroelectric material with high energy density.

Download or read book Study of Static and Dynamical Properties of Complex Antiferroelectrics Materials written by Kinnary Yogeshbhai Patel and published by . This book was released on 2021 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this dissertation is the investigation of the static and dynamical properties of the complex antiferroelectric materials using Effective Hamiltonian method and First principles calculations. In chapter 3, a novel elemental interatomic coupling in perovskite materials which bilinearly couples the antiferroelectric displacements of cations with the rotations of the oxygen octahedra. This new coupling explains a very complex crystal structure of prototypical antiferroelectric PbZrO3. My explanation provides a unified description of many other complex antipolar crystal structures in variety of perovskite materials, including the occurrence of incommensurate phases in some of them. In chapter 4, results and analysis of atomistic simulations explaining the dynamics of antiferroelectric distortions in BiFeO3 (BFO) bulk under hydrostatic pressure are reported. This system undergoes a phase transition on cooling from paraelectric Pm3 m̄ state at high temperatures to an intermediate P4/mbm phase followed by Pnma state at low temperatures. On the basis of my calculations, I prepared an analytical model of these phase transitions. The model developed can be easily applied to predict dynamics of antipolar cation motion in improper ferroelectrics. I found out that the antipolar modes do not soften themselves in the high temperature regime but they soften in the intermediate and Pnma phases, due to trilinear energetic coupling term. In chap- ter 5, the finite temperature behavior of the polar, antipolar, and antiferrodistortive phonons in a prototypical hybrid improper ferroelectric (BiFeO3)1/(NdFeO3)1 1:1 superlattice is studied. In the low-temperature phase, a spontaneous polarization appears due to trilinear coupling of structural and antiferroelectric (ferrroelectric) modes. In chapter 6, results of first-principles calculations to investigate and analyze properties of (001) thin films made of the most complex perovskite system, namely NaNbO3, are presented.Ferroelectric, antiferroelectric and antiferrodistortive properties of this thin film are reported and discussed, as a function of misfit strain.

This book was released on 2013-11-11 with total page 692 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a joint effort of the Research Materials Information Center (RMIC) of the Solid State Division at Oak Ridge National Laboratory and the Libraries and Information Systems Center at Bell Telephone Laboratories (BTL) Murray Hill, N. J. The Research Materials Information Center has, since 1963, been answering inquiries on the avail ability, preparation, and properties of inorganic solid-state research materials. The preparation of bibliographies has been essential to this function, and the interest in ferroelectrics led to the compila tion of the journal and report literature on that subject. The 1962 book Ferroelectric Crystals, by Jona and Shirane, was taken as a cutoff point, and all papers through mid-1969 received by the Center have been included. The Libraries and Information Systems Center of BTL has, over a period of years, developed a proprie tary package of computer programs called BELDEX, which formats and generates indexes to biblio graphic material. This group therefore undertook to process RMIC's ferroelectric references by BELDEX so that both laboratories could have the benefit of an indexed basic bibliography in this important research area.

This book was released on 2012-12-06 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The expansion of the application of ferroelectric crystals in engineering as well as of a number of fundamental problems of solid-state physics, which have not yet been solved and which bear a direct relation to ferro electricity, has lately stimulated much interest in the problem of ferroelectricity. In courses of solid-state physics ferroelectricity is studied today along with traditional disciplines, such as magnetism, superconductivity, and 'semiconducting phe nomena. Moreover, new specialities have been born concerned directly with the development and utilization of ferroelectric material~ in optics, acous tics, computer technology, and capacitor engineering. Special courses in the physics of ferroelectrics are read in a number of colleges and universities. The study of the nature of ferro electricity has currently reached such a level of development that we may speak of having gained a rather deep insight into the physical essence of a number of phenomena, which contribute to the generation of a spontaneous electric polarization in crystals. It is exactly at this level that it has become possible to single out that part of the problem, the physical picture of which can be depicted in a rather unsophisticated manner and which is the foundation for the construction of a building of "complete understanding".
