Birefringence induced by antiferroelectric switching in transparent polycrystalline film
Pranab Parimal Biswas, Cosme Milesi-Brault, Alfredo Blázquez Martínez +7
The most characteristic functional property of antiferroelectric materials is the possibility to induce a phase transition from a non-polar to a polar phase by an electric field. H…

Influence of charged walls and defects on DC resistivity and dielectric relaxation in Cu-Cl boracite
C. Cochard, T. Granzow, C. M. Fernandez-Posada +5
Charged domain walls form spontaneously in Cu-Cl boracite on cooling through the phase transition. These walls exhibit changed conductivity compared to the bulk and motion consiste…

Phaseseparation in overdoped Y_{1-0.8}Ca_{0-0.2}Ba_2Cu_3O_{6.96-6.98}
J. Röhler, C. Friedrich, T. Granzow +2
The dimpling in the CuO_2 planes of overdoped Y_{1-y}Ca_yBa_2Cu_3 O_{6.96-6.98} (y=0.02-0.2) has been measured by x-ray absorption-fine- structure spectroscopy (Y-K EXAFS). A step-…
