Both Conventional method and auto combustion methods were followed to synthesize powders of Barium titanate and Cobalt ferrite. Nowadays auto combustion synthesis has attracted much more attention due to the inexpensive precursors and ease of batch calculations. Unagglomerated fine powders can be obtained by auto combustion method. During preparation of BaTiO3 and CoFe2O4 by dry route they were calcined at 800o C for two hours and 1000o C for one hour respectively. Powders of Barium Titanate and Cobalt Ferrite synthesized by Auto combustion method were calcined at 1000o C for one hour and 1000o C for two hours respectively. Phases of particular compounds have been confirmed by XRD. For preparing multi ferroic composites the two separate powders are proved to be suitable.

This book is dedicated to modeling and application of magnetoelectric (ME) effects in layered and bulk composites based on magnetostrictive and piezoelectric materials. Currently, numerous theoretical and experimental studies on ME composites are available but few on the development and research of instruments based on them. So far, only investigation of ME magnetic field sensors has been cited in the existing literature. However, these studies have finally resulted in the creation of low-frequency ME magnetic field sensors with parameters substantially exceeding the characteristics of Hall sensors. The book presents the authors’ many years of experience gained in ME composites and through creation of device models based on their studies. It describes low-frequency ME devices, such as current and position sensors and energy harvesters, and microwave ME devices, such as antennas, attenuators, filters, gyrators, and phase shifters.

Magnetic, Ferroelectric, and Multiferroic Metal Oxides covers the fundamental and theoretical aspects of ferroics and magnetoelectrics, their properties, and important technological applications, serving as the most comprehensive, up-to-date reference on the subject. Organized in four parts, Dr. Biljana Stojanovic leads expert contributors in providing the context to understand the material (Part I: Introduction), the theoretical and practical aspects of ferroelectrics (Part II: Ferroelectrics: From Theory, Structure and Preparation to Application), magnetic metal oxides (Part III: Magnetic Oxides: Ferromagnetics, Antiferromagnetics and Ferrimagnetics), multiferroics (Part IV: Multiferroic Metal Oxides) and future directions in research and application (Part V: Future of Metal Oxide Ferroics and Multiferroics). As ferroelectric materials are used to make capacitors with high dielectric constant, transducers, and actuators, and in sensors, reed heads, and memories based on giant magnetoresistive effects, this book will provide an ideal source for the most updated information. Addresses ferroelectrics, ferromagnetics and multiferroelectrics, providing a one-stop reference for researchers Provides fundamental theory and relevant, important technological applications Highlights their use in capacitors with high dielectric constant, transducers, and actuators, and in sensors, reed heads, and memories based on giant magnetoresistive effects

Dielectrics is becoming increasingly important due to the rapid developments in electronics, optoelectronics, photonics and nanotechnology. In the past two decades, research on advanced dielectric materials and related applications has undergone an accelerated growth, due in larger part to the discovery of the superior piezoelectric properties in relaxor single crystals, the development of the lead-free piezoelectric/ferroelectric materials and the renaissance of the multiferroics.This book contains 9 feature articles which, together, provide a comprehensive account on the current state of advanced dielectrics and related phenomena. The first two articles present fundamental knowledge related to the characterization of ferroelectric hysteresis, which is the most widely used method to learn the ferroelectricity experimentally. The latest research progress in relaxor ferroelectric is given in the next two articles. The last five articles are dedicated to the multi-functionality of advanced dielectrics, with emphasis on multiferroic magnetoelectric composites, lead-free piezoceramics, pyroelectric/electrocaloric materials, polymer-based dielectrics, and flexible nanodielectrics.

This book presents current spatial and temporal multiscaling approaches of materials modeling. Recent results demonstrate the deduction of macroscopic properties at the device and component level by simulating structures and materials sequentially on atomic, micro- and mesostructural scales. The book covers precipitation strengthening and fracture processes in metallic alloys, materials that exhibit ferroelectric and magnetoelectric properties as well as biological, metal-ceramic and polymer composites. The progress which has been achieved documents the current state of art in multiscale materials modelling (MMM) on the route to full multi-scaling. Contents: Part I: Multi-time-scale and multi-length-scale simulations of precipitation and strengthening effects Linking nanoscale and macroscale Multiscale simulations on the coarsening of Cu-rich precipitates in α-Fe using kinetic Monte Carlo, Molecular Dynamics, and Phase-Field simulations Multiscale modeling predictions of age hardening curves in Al-Cu alloys Kinetic Monte Carlo modeling of shear-coupled motion of grain boundaries Product Properties of a two-phase magneto-electric composite Part II: Multiscale simulations of plastic deformation and fracture Niobium/alumina bicrystal interface fracture Atomistically informed crystal plasticity model for body-centred cubic iron FE2AT ・ finite element informed atomistic simulations Multiscale fatigue crack growth modeling for welded stiffened panels Molecular dynamics study on low temperature brittleness in tungsten single crystals Multi scale cellular automata and finite element based model for cold deformation and annealing of a ferritic-pearlitic microstructure Multiscale simulation of the mechanical behavior of nanoparticle-modified polyamide composites Part III: Multiscale simulations of biological and bio-inspired materials, bio-sensors and composites Multiscale Modeling of Nano-Biosensors Finite strain compressive behaviour of CNT/epoxy nanocomposites Peptide・zinc oxide interaction
