Unusual behavior of the ferroelectric polarization in PbTiO3/SrTiO3 superlattices.
Artificial PbTiO3/SrTiO3 superlattices were constructed using off-axis rf magnetron sputtering. X-ray diffraction and piezoelectric atomic force microscopy were used to study the evolution of the ferroelectric polarization as the ratio of PbTiO3 to SrTiO3 was changed. For PbTiO3 layer thicknesses larger than the 3-unit cell SrTiO3 thickness used in the structure, the polarization is found to be...

متن کاملShort-circuit boundary conditions in ferroelectric PbTiO3 thin films
We examine the application of short-circuit electrical boundary conditions in density-functional theory calculations of ferroelectric thin films. Modeling PbTiO3 films with metallic electrodes, we demonstrate that under periodic boundary conditions of supercells, short-circuit conditions for the electrodes are equivalently satisfied in two repeated slab geometries: a PbTiO3/metal superlattice g...
متن کاملNuclear Schiff moment in nuclei with soft octupole and quadrupole vibrations
Nuclear forces violating parity and time reversal invariance (P,T -odd) produce P,T -odd nuclear moments, for example, the nuclear Schiff moment. In turn, this moment can induce the electric dipole moment in the atom. The nuclear Schiff moment is predicted to be enhanced in nuclei with static quadrupole and octupole deformation. The analogous suggestion of the enhanced contribution to the Schif...
