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... -
From small compositional changes to large distortions - a new relaxor energy-...
[BiZn2/3NbO3]x-[BaTiO3]1-x for x up to roughly 0.2, known as BZN-BT is a complex made from one of the most studied materials in the world, BaTiO3 (BT), doped with Bismuth Zinc... -
Roles of magnetic anisotropy and inter site exchange interactions in the temp...
NdMnO3 exhibits A-type antiferromagnetism with TN =73 K. At 15 K, Nd sublattice orders with a (0, -Fy, 0) type ferromagnetic arrangement. Mn spin reorientation from (Ax, Fy, 0)... -
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... -
Magnetic structure of magnetocaloric manganites
Magnetic cooling has recently become the focus of cooling system technology as it boasts important advantages in terms of power consumption and for the environment e.g. not... -
First experiment with a pulsed field magnet at ISIS or how to break the 15T b...
We propose to use a pulsed magnet system tried and tested at several neutron and synchrotron facilities in conjunction with the new high flux diffractometer WISH to perform the... -
A high-temperature neutron powder determination of the phase transition and c...
Cu2ZnSnS4 (CZTS) is a solar cell material of great interest. However the material when fabricated, although of high symmetry, contains substantial defect concentration and a... -
Thermal expansion of hexa-halogenated benzenes: C6Cl6, C6Br6, C6I6.
The aim of the present proposal is to complete a systematic study on the effects of isotopic and chemical substitution on the thermal expansion and vibrational properties of... -
Compressibility and Tilting of Polyhedra within Sr2NiMoO6 at High Pressure
Ordered double perovskites (also known as elpasolites) have the general formula A2BBO6 where A is generally a rare earth metal or alkaline earth metal and where B and B are...
