We propose to perform high-resolution neutron diffraction on strained Ca3Ru2O7, a material in which electron correlations, spin-orbit coupling and crystal fields combine to...

Organic-inorganic lead halide perovskite compounds are shown to be very promising candidates for low cost, solution-processable, highly efficient (>22%) solar cells with a...

In the previous proposal we examined the ALC response of components of the complex dielectric under externally applied electric fields (EEF). We saw a shift in the asymmetry at...

Owing to their promising applications, especially in spintronics, multiferroics have been at the fprefront of condensed matter research for a number of years. In these...

We recently synthesised a new compound, K2Ni2(SO4)3, that allows the existence of non-trivial topologicalphases such as skyrmions. Specific heat measurements show the existence...

The proposing team is interested in exploring the rotational and translational dynamics of molecular hydrogen trapped in water-based cages (clathrate hydrates). These systems...

A better understanding of the magnetic excitation spectrum of LuFe2O4 is required to refine current models of the magnetoelectric coupling in this novel "electronic"...

It is possible that there is a coupling between the spin and gravitation, for instance by an adaptation of the Hamiltonian with an additional termH=k/c (gvec.Svec) where gvec is...

We propose to perform a systematic study of the intermolecular librational mode of molecular water in the proton conducting hydrated alkali thio-hydroxogermanates...

The study of novel manganites, where the tailoring of the Mn formal valence state on the B site is done by the ordering of different cations on the A site of the ABO3 (B:Mn)...

Our previous INS studies of ¿dry¿/hydrated apoferritin show that the hydrated protein undergoes a dynamical transition, Td, at 200K. Such behavior, first modeled by Doster et al...

Single crystal, bulk Si1-xGex alloys are available across the alloy composition range, and provide opportunity for study of alloy properties in transition between the two...

This proposal continues our investigations into polyelectrolyte-surfactant thin films which form at the air-solution interface. Our previous work investigated structure...

Croconic acid has recently emerged as the first example of an above room-temperature organic single component ferroelectric. Our goal is to determine its crystal structure at...

Gram-negative bacteria, which cause a variety of diseases including meningitis, plague, sepsis and food poisoning, are becoming increasingly antibiotic resistant. One reason is...

Liquid HCl has attracted numerous studies focusing onto the role played by hydrogen bonding on the dynamical properties of this weakly associated liquid. Previous computational...

Polar or non-centrosymmetric ferri(-o)magnets offer a plethora of potential technological devices; the inherent magnetoelectric effect can underpin both pyroelectric or...

Owing to their promising applications, especially in spintronics, multiferroics have been at theforefront of condensed matter research for a number of years. In these materials,...

We aim to continue our investigation of the high temperature magnetic interactions in LaCoO3. Our previous experiment has confirmed magnetic susceptibility data, with a change...

Replacing Na ions in NaxCoO2 with divalent Ca ions results in the formation of ordered arrays of divacancy clusters, rather than the trivacancy clusters found for the pure...
