Both 1D physics (dimensional frustration) and geometric frustration offer ways of achieving unusual quantum ground states that defy the usual tendency for systems to order at...

We had been given 1 day of beam time on WISH, RB1710144, to investigate the magnetic structure of T2V2O7 (T=Mn, Ni, Co) We performed power neutron diffraction measurements on...

Fischer-Tropsch (FT) catalysts offer a route to the production of fuels and chemicals from synthesis gas, which has a number of sources. This reaction is likely to play a key...

CeFe2Al10 belongs to the CeT2Al10 family (T: Ru, Os, Fe), which exhibits Kondo-insulator properties, with an unusual competition of strongly anisotropic crystal-field and...

The spin-chain systems with general formula A¿3ABO6, crystallizing in the K4CdCl6 type structure has attracted a lot attention in recent years due to geometrical frustration...

Flexible metal-organic frameworks (MOFs) such as Zn(C3H3N2) (ZIF-4) and Cu2(BBCDC) (DUT-49) show intriguing structural phase transitions when triggered by external stimuli such...

The appearance of non-dispersive Einstein (¿rattling¿) modes, known as the phonon-glass paradigm in filled-skutterudite compounds, has been postulated as an origin of the high...

In the current description of any molecular system based on the Schrodinger equation with a Hamiltonian accounting only for the electromagnetic forces, the structural properties...

For the RMn3O6 manganites, we have shown that tuning A-B exchange, by choice of A-site cation or by doping magnetic impurities, gives rise to dramatically different magnetic...

Spin ice (SI) is a state of matter characterized by a residual (Pauling) entropy and unusual correlations. The huge interest in SI materials from the magnetism community stems...

The proposed quasi elastic neutron scattering experiment at ISIS aims at the characterization of the dynamical properties of the series of coordination complexes Pr(BH4)3·nNH3,...

Water is crucial for the functioning of proteins. There has been substantial work to study the effect of water on protein dynamics, structure and function. However, how protein...

Several non-centrosymmetric heavy-fermion compounds have been reported to exhibit unconventional superconductivity (SC). For example, both CeRhSi3 and CeIrSi3 order...

We aim at studying proximity effects between a ferromagnetic thin film (either metallic or insulating) and a topological insulator (either undoped, or magnetically homogeneously...

We propose to use POLARIS to perform two related experiments. Firstly we will investigate the structures and compositions of derivatives of some layered Mn/Cu oxysulfides which...

Considering interesting physical properties observed in CeCuxAl4-x our aim is to investigate the stability of vibron excitations, already observed in CeCuAl3, as a function of...

The Methanol-to-Hydrocarbons reaction uses methanol as feedstock, and turns it into more industrially relevant products via a ZSM-5 catalyst. There is a lack of fundamental...

Ce3Co4Sn13 is a cubic heavy Fermion system which resides close to a magnetic instability.Under ambient conditions Ce3Co4Sn13 exhibits an extremely large (4 J/mol Ce K2) peak in...

We propose to study the powder averaged spin fluctuations in a S=5/2 pryochlore - FeF3. Previous studies, corroborated by our own diffraction work on WISH, have measured that...

Metal-organic magnets are of interest primarily due to the synthetic versatility enabled by the vast array of organic complexes which can be used to coordinate magnetic ions and...
