Incommensurate-commensurate phase transitions in K2SeO4
Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such... -
The structures of simple halogen bridged complexes
We propose a high-resolution neutron powder diffraction study of the complexes 1, 4-dioxane X2, where X = Cl, Br, I. These are the simplest halogen-bonded complexes in which a... -
Strain/order parameter coupling and anomalous elastic properties of Sr(Ti,Zr)...
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... -
Crystal Structures of Multiferroic MnWO4: HRPD
Multiferroic materials are rare and exceptional: they are ferroelectric and ferromagnetic in the same phase and these two properties can couple. Recently, materials with complex... -
Structural phase transitions in proton conducting BaCe0.8Y0.2O3-d as function...
The structure dependence of BaCe0.8Y0.2O3-d (BCY-20), a leading proton conducting material, will be studied as a function of temperature and, critically, controlled atmosphere... -
Magnetic and Structural Studies on Oxychalcogenides
In this proposal we request 3 days of beam time on HRPD to study the structures (both atomic and magnetic) of a variety of oxychalcogenide phases: La2O2Se2Fe2O, Ce2O2Se2Mn and...
