Perovskite-type compounds can be both very simple and tremendously complex. Remarkably, even binary perovskite-type compounds may exhibit high level of complexity that leads to...

Significant research has been given towards synthesis and characterisation of electrolyte materials with high proton conductivity for intermediate temperature range (200-600°C)...

Geometrically frustrated magnets have attracted great interest because of their exotic orders at low temperatures. In case of classical Kagome Heisenberg antiferomagnet its...

In this work, we will investigate the structures (crystallographic and magnetic) of Mn5VO8 and a range of Fe containing perovskite oxide fluorides. In terms of the former, this...

The aim of this experiment is to determine accurately the crystal structures of phases in the (1-x)BiScO3-xPbTiO3 (BST-PT) perovskite phase diagram, particularly in the vicinity...

HRPD data will be collected in situ at low and high temperatures from perovskites belonging to the Sr(ZrxTi1-x)O3 solid solution which have recently been characterised for their...

The recently reported double perovskite analogue imidazolium potassium iron(III) cyanide is noteworthy for two reasons. First, the order-disorder phase transitions, in which the...

The metal-organic framework perovskite analogue guanadinium copper(II) formate has achieved considerable recent attention for its multiferroic properties and consequent...

Pb2FeMO6 phases are of interest as potential multiferroics. We have prepared a new non-centrosymmetric pyrochlore-derived structure containing anion vacancy ordering...

Through low temperature fluorination of AFeO3-x (A=Sr, Ba) it is possible to prepare the oxide fluorides AFeO2F, which are antiferromagnetically ordered at room temperature. In...

Disorder of magnetic cations usually suppresses long-range spin order: the Curie or Néel temperature drops rapidly, and a spin glass state often results at high disorder levels....

Transition metal oxynitrides with perovskite type structures are an emerging class of materials with optical, photocatalytic, dielectric and magnetoresistive properties that may...

We propose to use Polaris to record powder neutron diffraction data for the oxygen deficient double perovskite Sr3SbO5.5 as a function of temperature to establish the...

To determine the temperature evolution of the structures of two Bi-based perovskites with commensurate structures through their magnetic transition temperatures to contrast...

The heat capacity and neutron powder diffraction measurements of the double perovskites La2NaB′O6 (B = Ru5+, Os5+) with S=3/2 on the B¿ reveal an incommensurate magnetic...

Our work on LSTN showed that it exhibits favourable electrochemical properties, i.e. rapid diffusion of lithium into the structure at low temperatures and the ability to...

Multiferroics - where ferroelectric and magnetic orders co-exist - continue to be of technological and scientific importance, and of particular interest are the improper...

It has always been assumed that CaSnO3 perovskite remains orthorhombic (Pbnm) as a function of temperature up to its melting point, and is rather unremarkable in many ways....

We request one day of beam-time on POLARIS to collect Neutron Diffraction (ND) data from three novel 12H-type hexagonal perovskites that exhibit higher than expected...

We have synthesised the ill characterised perovskite PbRuO3 at high pressure and temperature. Synchrotron powder x-ray diffraction shows the room temperature structure to be...
