Piezoelectric response of BiFeO3 ceramics at elevated temperatures

The high Curie temperature (T-C similar to 825 degrees C) of BiFeO3 has made this material potentially attractive for the development of high-T-C piezoelectric ceramics. Despite significant advances in the search of new BiFeO3-based compositions, the piezo ...

Room temperature concurrent formation of ultra-dense arrays of ferroelectric domain walls

Nava Setter, Alexander Tagantsev, Petr Yudin, Ludwig Feigl, Mahamudu Mtebwa, Konstantin Shapovalov

Properties of ferroelectric domain walls are attractive for future nano- and optoelectronics. An important element is the potential to electrically erase/rewrite domain walls inside working devices. Dense domain wall patterns, formed upon cooling through t ...

Controlling domain wall motion in ferroelectric thin films

Nava Setter, Alexander Tagantsev, Petr Yudin, Ludwig Feigl

Domain walls in ferroic materials have attracted significant interest in recent years, in particular because of the unique properties that can be found in their vicinity(1-3). However, to fully harness their potential as nanoscale functional entities(4,5), ...

Thickness Dependence of Domain-Wall Patterns in BiFeO3 Thin Films

Nava Setter, Tomas Sluka, Silviu Cosmin Sandu, Arnaud Robert André Crassous

Unique properties of domain walls in ferroelectrics have been recently discovered but methods of their controlled engineering remain underdeveloped. Here we investigate the domain structure of Bi0.9La0.1FeO3 epitaxial thin films with piezoelectric force mi ...

Moving antiphase boundaries using an external electric field

Nava Setter, Alexander Tagantsev, Petr Yudin, Konstantin Shapovalov, Kaushik Vaideeswaran

Antiphase boundaries (APBs) are unique domain walls that may demonstrate switchable polarization in otherwise non-ferroelectric materials such as SrTiO3 and PbZrO3. The current study explores the possibility of displacing such domain walls at the nanoscale ...

Temperature and field dependence of magnetic domains in La1.2Sr1.8Mn2O7

Colossal magnetoresistance and field-induced ferromagnetism are well documented in manganite compounds. Since domain wall resistance contributes to magnetoresistance, data on the temperature and magnetic field dependence of the ferromagnetic domain structu ...

On holography for (pseudo-)conformal cosmology

Sergey Sibiryakov

We propose a holographic dual for (pseudo-)conformal cosmological scenario, with a scalar field that forms a moving domain wall in adS(5). The domain wall separates two vacua with unequal energy densities. Unlike in the existing construction, the 5d soluti ...

Magnetic model in multiferroic NdFe3(BO3)(4) investigated by inelastic neutron scattering

Henrik Moodysson Rønnow

We performed inelastic neutron scattering measurements on single crystals of NdFe3((BO3)-B-11)(4) to explore the magnetic excitations, to establish the underlying Hamiltonian, and to reveal the detailed nature of hybridization between the 4f and 3d magneti ...

In Search of Ferroelectricity in Antiferroelectric Lead Zirconate

Kaushik Vaideeswaran

Since the prediction of antiferroelectricity and the subsequent discovery of PbZrO3, the description of antiferroelectric behaviour in materials has been constantly modified to account for the latest properties identified in antiferroelectric materials. Ad ...
