Electric-field-induced orthorhombic to rhombohedral phase transition in [111](C)-oriented 0.92Pb(Zn1/3Nb2/3)O-3-0.08PbTiO(3)

Dragan Damjanovic, Nava Setter, Matthew Davis

Strain-field measurements and in situ polarized light microscopy have been used to evidence a hysteretic, irreversible electric-field-induced transition to a quasimonodomain rhombohedral phase in 111-oriented, pseudo-orthorhombic PZN-8PT [0.92Pb(Zn1/3 ...

Enhancement of the piezoelectric response of tetragonal perovskite single crystals by uniaxial stress applied along the polar axis: A free-energy approach

Dragan Damjanovic, Nava Setter, Marko Budimir

The influence of the uniaxial bias stress on the piezoelectric properties of tetragonal BaTiO3 and PbTiO3 monodomain crystals is modeled in the framework of the phenomenological Landau-Ginzburg-Devonshire theory. It is shown that tensile and compressive st ...

Polarization microscopy by use of digital holography: application to optical- fiber birefringence measurements

Tristan Colomb, Etienne Cuche, Christian Depeursinge, Hans Georg Limberger, René Salathé, Pierre Marquet, Florian Dürr

We present a digital holographic microscope that permits one to image polarization state. This technique results from the coupling of digital holographic microscopy and polarization digital holography. The interference between two orthogonally polarized re ...

X-ray absorption, refraction and resonant scattering tensors in selenated protein crystals: implications for data collection strategies in macromolecular crystallography

Philip Pattison

Polarized fluorescence spectra were recorded in the vicinity of the Se and Br K edges on crystals of the selenated protein aldose reductase in complex with a brominated inhibitor molecule. The X-ray absorption, refraction and resonant scattering tensors as ...

X-ray ferromagnetic resonance spectroscopy

Harald Brune, Radivoje Popovic, Giovanni Boero, Pietro Gambardella, Stefano Rusponi

We present a method to measure continuous-wave ferromagnetic resonance (FMR) spectra based on the core-level absorption of circularly polarized x rays. The technique is demonstrated by using a monochromatic x-ray beam incident on an yttrium-iron-garnet sam ...

Correlation between dielectric anisotropy and positive or zero transverse piezoelectric coefficients in perovskite ferroelectric single crystals

Dragan Damjanovic, Nava Setter, Matthew Davis

The transverse piezoelectric coefficient (d(31)(star)) has been calculated for tetragonal barium titanate (BT) and lead titanate (PT) cut along nonpolar axes, over a range of temperatures, using the phenomenological Landau-Ginzburg-Devonshire theory. It is ...
