Field-induced switching of tetragonal domains in SrTiO3 at low temperatures

Low-Temperature Dielectric Anisotropy Driven by an Antiferroelectric Mode in SrTiO3

“…4(b)] clearly differ. Our conclusions on the dielectric anisotropy are in good agreement with the available experimental literature [7,47,49] and earlier theoretical studies [38]. Also, the fast decrease of the dielectric susceptibility of SrTiO 3 with temperature and the ensuing reduction of polarizability is likely responsible for the increasingly hindered ferroelastic twin motion as the transition temperature is approached (see Fig.…”

Quantitative determination of domain distribution in SrTiO3—competing effects of applied electric field and mechanical stress

“…Although a direct coupling between the antiferrodistortive order parameter and the electric field is forbidden by symmetry, a clear indication of domain redistribution was observed. While indications of such behaviour were mentioned even in the 1970s [15,16], to the best of our knowledge a thorough investigation has not been performed so far.…”

“…We have carefully determined the integrated intensities of the set of SLRs listed in table 2. Different approaches have been applied to determine the volume fractions of the three domains: on the one hand, the volume fractions were directly calculated from each of the groups of reflections (1-3), (4-6), (13)(14)(15). The full set of SLR-intensities, on the other hand, was used for a fit by the volume fractions according to equation (2).…”

Konkurrierende ferroische Ordnungsparameter in SrTiO3: Domänenverhalten und Schaltverhalten

“…Dabei sind auch elektrische Felder in der Lage die Domänenverteilung zu beeinflussen. Erste Hinweise auf eine feldabhängige Domänenverteilung wurden bereits 1972 von Pietrass geliefert [77]. Er interpretierte das von Saifi und Cross [78] beobachtete elektrische Hystereseverhalten der Dielektrizitätszahl bei 4.2 K als das feldinduzierte Schalten zwischen verschiedenen tetragonalen Domänen.…”
