Highly ordered Cl(-) and SO4(2-)-intercalated layered double hydroxides (LDHs) of Cu(II) and Cr(III) are obtained when coprecipitation is carried out at low pH ~ 5 and elevated temperature (60-80 °C). Precipitation under other conditions results in the formation of a gel. The SO4(2-)-LDH exhibits weak reflections which could be indexed to the 100 and 101 planes of a supercell corresponding to a...

Recently, the ferroelectromagnet YMnO3 has been the focus of interest because it exhibits both antiferromagnetism (Néel temperature ∼ 80 K) and ferroelectricity (Curie temperature ∼ 914 K). There have been no reports of complete YMn1−xMxO3 solid solutions in which substitution of the foreign M cation preserves the hexagonal P63cm structure. In contrast there exist several homeotypic phases with...

In this study, multilayered PbTixZr1-xO3 (PZT) samples were produced by tape-casting and subsequent sintering at temperatures in the range of 1175 °C to 1325 °C. Sintering times were 6 and 24 minutes. Samples were poled and additionally electrically fatigued by long-term exposure (≈10 cycles) to cyclic electric fields. The parameters of initial and remnant polarization were estimated from hyste...

Incorporation of Mo into pure WO3 thin films is interest for electrochromic devices, as it improves colour neutrality in the dark state. Existing literature still lacks reliable quantitative data on complex dielectric function such coatings. In this study, we deposited and MoxW1?xO3 by magnetron sputtering subsequently characterised them X-ray photoelectron spectrometry (XPS), grazing incidence...
