Multiferroic (Ferroelastic/Magnetic) Phase Transitions in KMnF3
KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling... -

Magnetic ordering and structure phenomena in the rare-earth CeRu2Al10 compound.
This proposal is for crystal-structure (on HRPD) and magnetic ordering (on WISH) studies on the local-moment compound CeRu2Al10. It follows from our recent neutron studies at... -
Unravelling Structural Complexity within a Family of Frustrated S = ½ Kagome ...
Quantum spin liquids (QSLs) are exotic states of matter in which magnetic frustration and strong quantum fluctuations destroy long-range magnetic order. Here, we propose to... -

Improper ferroelectricity in hexagonal tungsten bronzes
We address the detailed atomistic mechanism of ferroelectricity in a new family of oxides typified by the composition CsNbW2O9. Contrary to the mechanism in most ferroelectrics,... -
The role of Disorder in Phase Transitions in some manganese Perovskites
The aim of this work is to understand the origin of the difference in the behaviour between the two doped manganites Sr0.65Pr0.35MnO3 and Sr0.70Ce0.30MnO3. The hypothesis we... -
Structural characterisation of new thermoelectric oxide solid solutions
Thermoelectrics are materials that produce a voltage when subjected to a thermal gradient, and can therefore be used to generate electricity from waste heat. Such materials are... -
The Magnetic Structure of LaCoxMn1-xO3 (x = 0.75)
It is the aim of the current proposal to examine in detail the magnetic structure of LaCo0.75Mn0.25O3 at low temperature, which should provide insight into the nature of the... -
Characterisation of the low temperature phase transition in Pb(CD3COO)2 .3D...
We propose to use high resolution neutron powder diffraction for the study of the nuclear structure of Pb(CD3COO)2.3D2O in its low-temperature phase and to characterise with... -
The structures of PZT in its ¿rhombohedral¿ phases and their dependence on th...
In the piezoelectric ceramic material PbZrxTi1-xO3 (PZT) there is controversy about the structure of PZT at the Zr-rich end. This region has always been considered to be of... -
The ferroelectric phase transition in Dion-Jacobson layered perovskites - con...
Ferroelectricity in the Dion-Jacobson (DJ) family of layered perovskites arises from a 'trilinear coupling', whereby two non-polar lattice modes interact in such a way to... -
Kinetics of the ordering transition in ice Ih; crystal structure and thermal ...
Below 80 K ordinary water ice (ice Ih) undergoes a phase transition in which the randomly oriented molecules in the crystal adopt an ordered orientation. This ordered form of...
