Single-phase magnetoelectric multiferroics are ferroelectric materials that display some form of magnetism. In addition, magnetic and ferroelectric order parameters are not independent of one another. Thus, the application of either an electric or magnetic field simultaneously alters both the electrical dipole configuration and the magnetic state of the(More)
A thermodynamic analysis of the electrocaloric ͑EC͒ effect in BaTiO 3 ferroelectric thin films has been carried out under differing mechanical boundary conditions. It is shown that both the magnitude of the electrocaloric effect and temperature at which it is maximized depend not only on the extent of the applied field change but also on the value of the(More)
This addendum documents change made to the ATBD between V2.0 and V3.0 of the Aquarius L2 salinity retrieval algorithm which was implemented in January, 2014 and that will be released to the public through the JPL PO.DAAC in March, 2014. The code was updated to include all the changes and then the entire data set was rerun. The algorithm changes that were(More)
Elastic and anelastic properties of ceramic samples of multiferroic perovskites with nominal compositions across the binary join PbZr0.53Ti0.47O3-PbFe0.5Ta0.5O3 (PZT-PFT) have been assembled to create a binary phase diagram and to address the role of strain relaxation associated with their phase transitions. Structural relationships are similar to those(More)
In an attempt to explore fundamental aspects of the behaviour of ferroelectrics at reduced dimensions, a focused ion beam microscope has been used to cut thin sheets, or lamellae, and nanowires directly from single crystal BaTiO3. Permittivity characteristics and the nature of domain configurations adopted have been investigated. While the permittivity of(More)
Monodomain contributions to the electrocaloric effect in mechanically free (bulk) and laterally strained (thin film) BaTiO3 are computed using a thermodynamic analysis. We show that the intrinsic electrocaloric coefficient at electric fields sufficient to destroy the discontinuous ferroelectric phase transition results in an adiabatic temperature change of(More)
Pb(Zr,Ti)O<sub>3</sub> (PZT) thin films and nanotube were prepared on SiO<sub>2</sub>/Si substrates by liquid source misted chemical deposition (LSMCD) using Samco MD-6060 apparatus. We report the deposition and characterization of transparent ferroelectric thin films and nanotubes. PZT thin films deposited at ambient conditions and annealing at 700degC(More)
Several fundamental physics problems concerning ferroelectric thin films are discussed with direct application to industry problems. The first is a model of dielectric breakdown under d.c. voltage stressing, extended from single capacitor films to multilayer capacitors (MLCs). The second is an analysis of flash-over (arcing) breakdown in MLCs, including(More)
New approaches to thermal management of electronic components are of general interest. Our work demonstrates a novel solution for this applications area. Highly effective thermal management solutions can potentially help the semiconductor manufacturers to reduce costs and meet some milestones of the silicon roadmap. For example, enormous amount of Joule(More)
