Vortices and antivortices in antiferroelectric PbZrO3
Ying Liu, Huazhang Zhang, Konstantin Shapovalov +8
Although ferroelectric materials are characterised by their parallel arrangement of electric dipoles, in the right boundary conditions these dipoles can reorganize themselves into…
The incredible diversity of structural and magnetic instabilities in EuTiO3: from paramagnetic to spin glass, spin liquid and antiferromagnetic order
Annette Bussmann-Holder, Reinhard K. Kremer, Efthymios Liarokapis +1
The perovskite oxide EuTiO3 (ETO) has attracted increased scientific interest due to its potential multiferroic properties and magnetic activity above and below its structural phas…
Translational boundaries as incipient ferrielectric domains in antiferroelectric PbZrO3
Ying Liu, Ranming Niu, Andrzej Majchrowski +4
In the archetypal antiferroelectric PbZrO3, antiparallel electric dipoles cancel each other, resulting in zero spontaneous polarisation at the macroscopic level. Yet in actual hyst…
Ferroelectric to incommensurate fluctuations crossover in PbHfO3-PbSnO3
Maria A. Kniazeva, Alexander E. Ganzha, Irena Jankowska-Sumara +6
Perovskite solid solutions PbHfO3-PbSnO3 offer valuable opportunities for studying the formation mechsnisms of incommensurate phases, owing to the presence of an intermediate (betw…
Filamentary superconductivity of resistively-switched strontium titanate
K. Szot, C. Rodenbücher, K. Rogacki +7
SrTiO, although a wide gap insulator, has long been known to become metallic and superconducting at extremely low doping levels. This has given rise to questions concerning the…
Direct visualization of antiferroelectric switching dynamics via electrocaloric imaging
Pablo Vales-Castro, Miquel Vellvehi, Xavier Perpiñà +8
The large electrocaloric coupling in PbZrO3 allows using high-speed infrared imaging to visualize antiferroelectric switching dynamics via the associated temperature change. We fin…
Origin of the Large Negative Electrocaloric Effect in Antiferroelectric PbZrO3
Pablo Vales-Castro, Romain Faye, Miquel Vellvehi +9
We have studied the electrocaloric response of the archetypal antiferroelectric PbZrO3 as a function of voltage and temperature in the vicinity of its antiferroelectric-paraelectri…
Unconventional co-existence of insulating nano-regions and conducting filaments in reduced SrTiO3: mode softening, local piezoelectricity and metallicity
Annette Bussmann-Holder, Hugo Keller, Arndt Simon +2
Doped SrTiO3 becomes a metal at extremely low doping concentrations n and is even superconducting with the superconducting transition temperature adopting a dome-like shape with th…
Flexoelectricity in antiferroelectric ceramics
P. Vales-Castro, Krystian Roleder, Lei Zhao +3
Flexoelectricity (coupling between polarization and strain gradients) is a property of all dielectric materials that has been theoretically known for decades, but it is only relati…
Transparent EuTiO3 films: a novel two-dimensional magneto-optical device for light modulation
Annette Bussmann-Holder, Krystian Roleder, Benjamin Stuhlhofer +6
The magneto-optical activity of high quality transparent thin films of insulating EuTiO3 (ETO) deposited on a thin SrTiO3 (STO) substrate with both being non-magnetic materials are…
Lattice dynamics and antiferroelectricity in PbZrO tested by X-ray and Brillouin light scattering
R. G. Burkovsky, A. K. Tagantsev, K. Vaideeswaran +13
We report the results of comprehensive study of the critical dynamics of the prototype perovskite antiferroelectric PbZrO. The combination of inelastic X-ray and diffuse X-ray…
Elastic Anomalies Associated with the Antiferroelectric Phase Transitions of PbHfO3 Single Crystals
Jae-Hyeon Ko, Krystian Roleder, Andrzej Majchrowski +1
The temperature dependence of the elastic properties of antiferroelectric PbHfO3 was investigated by Brillouin scattering. The two structural phase transitions of antiferroelectric…
