Evolution of magnetic ordering in the layered oxide arsenide Sr2CrO3CrAs
This experiment will probe the evolution of magnetic ordering in Sr2CrO3CrAs, a compound containing Cr2+ moments in arsenide layers and Cr3+ moments in oxide layers. We will use... -
Dynamical disorder or incipient nano-ferroic distortions in CaSnO3 perovskite?
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.... -
Evolution of magnetic ordering in three oxide arsenides containing CrO2 layer...
This experiment will probe the evolution of magnetic ordering in compounds with square planar Cr2+ ions in CrO2 oxide layers, and the interaction of these moments with Mn2+ and... -
The structure of hydrogen in calcium-ammonia-graphite: an in situ time resolv...
The aim of this proposal is to determine the in-plane and out-of-plane structure of H2 in the two dimensional galleries of stage-I calcium-ammonia-graphite intercalates: this... -
Does elastic twinning play a role in the thermal expansion behaviour of polyc...
We request two days of beam-time on POLARIS to obtain high resolution measurements of the thermal expansion of dolomite [CaMg(CO3)2]. The experiment forms part of a larger...
