Cation and spin orders in double double perovskites
Our recent neutron study showed that CaMnFeReO6 has a recently discovered double double perovskite structure type with cations ordered across 3 distinct A-sites in columns... -
Single proton short time dynamics in Pd/Ag membranes
Pd-Ag membranes used in Fusion machines for isotopic separation of H isotopesa can also be used for the production of ultrapure H with interesting applications in renewables.... -
Inelastic neutron scattering spectra of hydrogen absorbed in palladium-silver...
Pd-Ag alloys find technological applications in H uptake and purification. Among various peculiar properties, their electric resistivity variation as a function of the H loading... -
Neutron spectroscopy in mononuclear Ni(II) complexes
Mononuclear Ni(II) complexes can be designed to behave as two-level systems and thus play the role of qbits with eventually large coherence time. The objective of this proposal... -
The coupling of spin and charge correlations in La2-xSrxCuO4
Charge density wave (CDW) order has recently been established as a generic feature of high-temperature cuprate superconductors. It occurs near 1/8 doping and has been observed... -
Structural investigations of low-temperature "trapped solutions" of C60 fulle...
We propose a series of neutron scattering measurement to determine the water structure in amorphous H2O/C60 fullerene vapour deposits. We believe that these samples, prepared by... -
Investigation of modulated crystal and magnetic structure of Ni-Pt-Mn-Ga ferr...
Ferromagnetic shape memory alloys (FSMAs) are of recent interest because they exhibit a shapememory effect that can be driven by magnetic fields. Thus, FSMAs are important for... -
A High-Pressure Low-Temperature Crystallographic Study of the Pm3m - I4/mcm F...
The perovskite-structured phases and their associated phase transitions remain an enduring topic of study within the solid state sciences due to their importance in both applied... -
Inelastic neutron scattering investigation of the giant phonon anomalies due ...
The electron-phonon interaction is a major factor influencing the competition between collective instabilities in correlated-electron materials, but its role in driving... -
Paramagnetic excitations in BaFe2As2 at high temperature
One fundamental issue in the iron-based superconductors is whether the conventional local moment Heisenberg model is sufficient to describe magnetism in these materials, or... -
High-Energy dynamics and search for a continuum in CaFe2O4
We propose to investigate the high-energy (above 10 meV) excitations using either the MERLIN or MAPS chopper instruments. CaFe2O4 is interesting for several reasons. First, it... -
The Second Critical Point and Widom line of supercooled confined water
In 1992 P. Poole and coworkers have proposed the existence of two water polymorphs below its homogenous nucleation temperature. These are separated by a coexistence line ending... -

Dynamics within the Plastic Crystal Phases of Hydrogen Chloride
Hydrogen chloride exhibits a complex phase diagram account made of its simple molecular structure. Three crystalline phases are known to exist at ambient pressure below its... -
Low temperature phases of WO3 a reinvestigation
WO3 is an important technological material with wide usage in gas-sensing devices but its low temperature phases are still mysterious. There are conflicting reports in the... -
Neutron inelastic scattering of the possible quantum spin ice state of Nd2Zr2...
Nd2Zr2O7 is a new candidate for quantum spin ice proposed theoretically. It has a well-isolated dipolar-octupolar doublet with Ising anisotropy as the crystal field ground state... -
Anomalous fast diffusion of Cu ions in superionic and liquid phases of CuI
CuI is well-known to exhibit the superionic behaviour in the high temperature solid state (α-phase), where the mobile Cu ions migrate among the interstices in the f.c.c.... -
Phase behaviour of methane clathrate under conditions relevant to Titan's int...
Methane clathrates are likely to be an important constituent of icy satellite interiors and a source of methane in the atmosphere of Saturn's giant satellite Titan. There is... -
Search for new hydrogen, helium and neon hydrates at high pressure
This proposal is for time to search for predicted gas hydrates at high pressure. The results will provide insight into the factors governing the stability of the H-bonded... -
Investigation of magnetic ordering in a new spin liquid candidate
PbCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu2+ ions coupled by 3 interactions. The 1st neighbor interaction couples Cu2+ into isolated triangles, 2nd nearest...
