The family of guanadinium metal formates (M=Mn, Fe, Co, Ni, Cu) are isostructural with the perovskites and are therefore of interest for potential applications: in particular,...

The magnetism of double perovskites can be amazingly sensitive to subtle distortions of their structures. Previous studies have shown that Ca2NiOsO6 is a ferrimagnet, Sr2NiOsO6...

We propose to study the temperature dependence of the inelastic response of BaCoO3. This system gives the experimental evidence of a new partially disordered antiferromagnetic...

In a successful recent experiment on IN5 (ILL), we have been able to show that in contrast to commonly accepted wisdom, the excitation gap in nearly optimally doped...

BiFeO3 is a room temperature multiferroic, displaying both ferroelectric and antiferromagnetic (AFE) ordering. x-BiFeO3 - (1-x)-PbTiO3 is also multiferroic at room temperature...

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....

The proposal addreses the compounds PrPtAl and YbNiSn. Both systems are canted ferromagnets with both materials undergoing moment reorientation transitions as a function of...

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....

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...

In the coming year, we plan to build upon the success of last cycle by carrying out more hydrocarbon studies of this porous material NOTT-300 and one of its iso-structural...

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...

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...

TlCoCl3 and Tl FeCl3 undergo structural phase transition at T1= 165K, respectively T1= 179K and T2=75 K, respectively 79 K. The unit cell stay hexagonal but the basic unitcell...

Inelastic neutron scattering has proven to be reliable tool to investigate the phonon structure of hydrides. E.g., it was shown that the vibrational structure of Ca(BH4)2 has a...

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...

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....

Exotic electronic states are of great interest to fundamental science, such as the quantum spin-liquids (QSLs) which were theorised to behave like a sea of resonating spin...

High resolution powder diffraction data will be used to obtain lattice parameter and atomic coordinate variations as a function of temperature for Pr0.6Ca0.4MnO3, which has a...

We propose to study by powder neutron diffraction the ordered magnetic state of the pyrochlore compound Y2Ir2O7. There is currently an increasing interest in the condensed...

This proposal will measure vibrational spectra from a series of catalyst samples produced from a pilot plant reactor at Tianjin University China converting dimethylether to...
