Structural Origin of the Metal-Insulator Transition of Multiferroic BiFeO3
S. A. T. Redfern, J. N. Walsh, S. M. Clark +2
We report X-ray structural studies of the metal-insulator phase transition in bismuth ferrite, BiFeO3, both as a function of temperature and of pressure (931 oC at atmospheric pres…
Magnetoelastic-magnetoelectric phase transitions in multiferroic BiFeO3
S. A. T. Redfern, C. Wang, J. W. Hong +2
Our measured dielectric constant and mechanical response of multiferroic BiFeO3 indicate four phase transitions below room temperature. Features correlate with those reported at 50…
Conformal oxide coating of Carbon Nanotubes
S. Kawasaki, G. Catalan, H. Fan +8
The International Roadmap for Ferroelectric Memories requires three-dimensional integration of high-dielectric materials onto metal interconnects or bottom electrodes by 2010. We r…
Smallest 90o domains in epitaxial ferroelectric films
A. H. G. Vlooswijk, G. Catalan, A. Janssens +7
Ferroelectrics display spontaneous and switchable electrical polarization. Until recently, ferroelectricity was believed to disappear at the nanoscale; now, nano-ferroelectrics are…
Domains in Three-dimensional Ferroelectric Nanostructures: Theory and Experiment
G. Catalan, J. F. Scott, A. Schilling +1
Ferroelectric random access memory cells (FeRAMs) have reached 450 x 400 nm production (0.18 micron^2) at Samsung with lead zirconate-titanate (PZT), 0.13 micron^2 at Matsushita wi…
Universality of the Scaling Law for Ferroic Domains
G. Catalan, J. F. Scott, A. Schilling +1
We show how the periodicity of 180^{o} domains as a function of crystal thickness scales with the thickness of the domain walls both for ferroelectric and for ferromagnetic materia…
