Voltage-controlled ferroelastic switching in Pb(Zr0.2Ti0.8)O3 thin films

We report a voltage controlled reversible creation and annihilation of a-axis oriented 10 nm wide ferroelastic nanodomains without a concurrent ferroelectric 180° switching of the surrounding c-domain matrix in archetypal ferroelectric Pb(

Vacuum-ultraviolet ellipsometry spectra and optical properties of Ba(Zr,Ti)O3 films

In this work, we determine the dielectric functions of multi-target, reactively sputtered Ba(Zr0.2Ti0.8)O-3 by spectroscopic ellipsometry in the photon energy range from 0.8 to 8.7 eV. Based on this data, we discuss the interband transition ...

Magnetic interactions in disordered perovskite PbFe1/2Nb1/2O3 and related compounds: dominance of nearest-neighbor interaction

From theoretical calculations and modeling the main magnetic interactions were determined in Pb(Fe1/2Nb1/2)O3 and related compounds. It was shown dominance of nearest-neighbor interaction. The relatively high temperature of AFM tran...

Lead Excess in Pb(Zr,Ti)O3 Thin Films Deposited by Reactive Sputtering at Low Temperatures

Pb(Zr,Ti)O3 thin films deposited by multi-target reactive sputtering at low substrate temperatures are charecterized by a significant lead excess without a measurable second phase......

Dynamical coupling in Pb(Zr,Ti)O3 solid solutions from first principles

A first-principles-based approach is developed to model dynamical coupling between different degrees of freedom in the terahertz frequency range at any temperature. Such an approach is applied to Pb(Zr,Ti)O3 alloys, which exhibit bo...

93Nb NMR and Fe3+ EPR study of local magnetic properties of magnetoelectric Pb(Fe1/2Nb1/2)O3.

The 93Nb NMR and Fe3+ EPR spectra of a magnetoelectric Pb(Fe1/2Nb1/2)O3 (PFN) single crystal as well as of PFN ceramics and nanopowder have been measured. The relation between the chemical disorder and the local magnetic structure h...

17O and 93Nb NMR investigation of magnetoelectric effect in Pb(Fe1/2 Nb1/2)O3./sub

The 17O and 93Nb quadrupole perturbed NMR spectra of multiferroic Pb(Fe1/2Nb1/2)O3 have been measured. The results show that the ordering at TN = 143 K is antiferromagnetic with spin canting and that there is another magnetic transi...

Investigation of the RF pulse modulated plasma jet system during the deposition of Pb(ZrxTi1-x)O3 thin films on polymer substrates

The RF modulated plasma jet system was investigated during the deposition of Pb(ZrxTi1-x)O3 (PZT) thin films on polymer substrates. PZT films were deposited simultaneously on Si and polymer substrates with Pt layer. PZT films were d...
