Damping Behavior in Ferroelectric Reinforced Metal Matrix Composites
… behavior of FR-MMCs created by the addition of barium titanate (BaTiO3) discontinuous reinforcement in a bearing bronze (Cu-10w%Sn) matrix has been studied. It has been shown that even when combined with other traditional composite mechanisms, added damping ability has been achieved due to the …

Barium Titanate-Based Magnetoelectric Nanocomposites
Barium Titanate (BaTiO3 or BTO) has attracted an ever increasing research interest because of its wide range of potential applications. Nano-sized or nanostructured BTO has found applications in new, useful smart devices, such as sensors and piezoelectric devices. Not only limited to one material, …

Self-Assembled Barium Titanate Nanoscale Films by Molecular Beam Epitaxy
… during growth. Historically, the growth of barium titanate (BaTiO3) by molecular beam epitaxy has relied on a growth technique called shuttered RHEED. Shuttered RHEED controls the stoichiometry of barium titanate through the precise deposition of alternating layers of BaO and TiO2. While …

Investigating Ferroelastic and Piezoelectric Vibration Damping Behavior in Nickel-Barium Titanate and Nickel-PZT Composites
… ferroelectric and piezoelectric ceramics such as barium titanate (BaTiO3) and lead zirconate titanate (PZT) is due to the anelastic response of ferroelastic domain walls to applied external stress. In piezoelectric ceramics, vibration energy can also be dissipated through the direct piezoelectric …

Chemical vapor deposition of thin film materials for electronic and magnetic applications
… ferrite (NiFe2O4), lithium ferrite (LiFe5O8) and barium titanate (BaTiO3) films on various lattice match substrates. For the deposition of nickel ferrite, anhydrous Ni(acac)2 and Fe(acac)3 (acac = acetylacetonate) are used as precursor sources dissolved in N,N-dimethyl formamide (DMF) for the DLI …

New modalities for strain engineering of lead-free perovskite ferroelectric thin films
… of lead-free ferroelectrics such as BiFeO3, BaTiO3, and others. Previous work on epitaxial BiFeO3 thin films have shown that large compressive strains can drive the formation of complex mixed-phase structures with enhanced electromechanical responses (4-5% strains). In this work, we probe the …
