20 years ago, Anderson proposed that the thermoelastic properties of the dominant (mantle) phase within the Earth, MgSiO3 perovskite, could be described as a simple Debye solid....

This proposal seeks to investigate the effect of temperature on the structures of thallium and caesium azide. High-resolution neutron powder diffraction data are necessary to...

This proposal is to explore the evolution of magnetic ordering in two members of the homologous series CaFe2O4(FeO)n with n = 1, & 3, and to correlation the behaviour of the...

YbAgGe has an enhanced electronic specific heat coefficient and two magnetic phase transitions at TM1=0.8K and TM2=0.65K. We have grown a series of TbxYb1-xAgGe and YbAgGe...

R2RuO5 (R = Pr, Nd, Sm, Gd, Tb) are known to exhibit interesting physical properties. They all show magnetic ordering between 8 ¿ 24 K. They also show large Sommerfeld...

The defect thiospinel, GeV4S8 adopts a cubic structure at room temperature (space group F-43m). We have identified a new monoclinic phase of this material at 2K, which may be...

We seek to develop new stable MOFs for practical separation and storage of CO2 and light hydrocarbons and request 3 days on WISH to study the preferred binding sites of adsorbed...

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...

LiFeCr4O8 (LFCO) crystallizes in a cubic spinel structure with a noncentrosymmetric space group (F4 ̅3m), where Li+ and Fe3+ ions are ordered in zinc-blend type manner at...

With the overall aim of extending the information derivable in a neutron single crystal diffraction experiment beyond the static structure, we are proposing to perform a...

I am working on a low dimensional quantum magnet family. A member of it, KNb, is a good experimental realisation of the squarelattice. It appears that this compound has a...

Sr3Ru2O7 is a layered Ruddlesden-Popper perovskite which displays intriguing behaviour at low temperatures and high magnetic field. It can be tuned close to a quantum critical...

Amorphous polymorphism is one of the key concepts in our understanding of water, its structure, physical properties and anomalies. The basic idea is that liquid water at ambient...

The physical properties of the post-perovskite phase of MgSiO3 control the dynamics of the lower thermal boundary layer of the Earth¿s mantle, but many of these properties...

Halogenomethane derivatives exhibit thermally induced solid¿solid phase transitions before melting that are attributed to the ability to gain rotational degrees of freedom in...

The interplay between spin, charge, orbital, and lattice degrees of freedoms in SrMn1-xWxO3 (X= 0.1625, 0.175) produce the charge and/or spin density waves (CDW, SDW) modulated...

Ammonia Borane (AB), NH3BH3, was first synthesised in the 1950s and has now become the focus of a world wide research program with regards to its potential as a hydrogen store....

Ba3BiIr2O9 and Ba3BiRu2O9 undergo very unusual structural transitions at 74 and 176 K respectively, with instantaneous negative thermal expansion of up to 1% in the Ir compound....

BiFeO3 is the most widely studied multiferroic and rare earth doping overcomes problems associated with phase metastability and leakage which have hampered applications. We...

This experiment will investigate three related systems which contain copper deficient anti-fluorite-type copper sulfide layers. The overall aim is to correlate magnetic and...
