Magnetic structure of noncentrosymmetric CeZnAl3
The Ce-based materials CeTX3 (T=transition metal, X= Si, Ge, Al) crystallizing in the noncentrosymmetric BaNiSn3-type structure, have been found to display a wealth of novel... -
Stochastic vs. Intermolecular Motions in Strongly Associated Liquids: The Cas...
Neutron scattering is a powerful technique to study stochastic motions in liquids but it requires an energy resolution well below the meV range. As a consequence, quasielastic... -
Gaps in the spin wave dispersion relation in elemental iron
Iron is a canonical instance of an itinerant electron ferromagnet, and a classic correlated electron system. Our recent data from MAPS contradicts earlier triple-axis data that... -
Pressure dependence on the isomorphic phase transition in KOs2O6
We are requesting 5 days of beamtime on HRPD to measure powder diffraction patterns of KOs2O6 under He gas high pressure up to 150 MPa. KOs2O6 exhibits a novel phase transition... -
Structure and Magnetism of Rb1-xFe2F6: Tuning the Valence of Charge-Ordered K...
We have recently discovered a new family of geometric frustrated magnets starting from the parent system, RbFe2F6, with crystallizes in the defect or β-pyrochlore structure... -
Structural Studies of PbZr1-xTixO3: completing the puzzle in the tetragonal a...
We request 6 days of HRPD time in order to study the structures on the tetragonal side of the lead zirconate-titanate (PZT) phase diagram, a region that has so far been rather... -

Uptake of Molecular Hydrogen by High-performance Carbon Nanostructures (IRIS)
High sorption capacities and enhanced interaction strengths are the two most fundamental prerequisites for the deployment of carbon-based materials as hydrogen-storage media. In... -
Determining the Crystal and Magnetic Structures of [Li(oxalate)]2[Co5(OH)8]
Dense corrdination frameworks that contain inorganic centres connected into extended lattices by polyatomic anions often adopt highly anisotropic structures. Thus they often... -
The Dynamics of Molecular Hydrogen in Synthetic Clays
In this proposal we aim to study the low temperature uptake and dynamics of hydrogen in the interlayer region of partially hydrated pillared clays. There are linked dual... -

1D magnetic structure of a multiferroic metal-formate perovskite
The metal-organic framework perovskite analogue guanadinium copper(II) formate has achieved considerable recent attention for its multiferroic properties and consequent... -
Temperature Effects in YIG Films Probed by PNR
Yttrium iron garnet Fe3Y5O12 (YIG) is the material of choice for spin Hall related effects, magnonics, inter alia and has been used in microwave applications for many years.... -

Hydrogen dynamics in clay nanotubes
We will study H2 dynamics in the nanotubular clay imogolite whose structure has an external diameter of ~2.5 nm and an inner diameter of <1 nm. The tube length of synthetic... -
The Structure of the High-Energy ¿Paramagnon¿ Excitations in La2-xSrxCuO4
A major problem in physics is the identification of the mechanism of high-temperature superconductivity. Many theories purport to explain the high-Tc phenomenon. In most... -
Multiferroic (Ferroelastic/Magnetic) Phase Transitions in KMnF3
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... -
Low-Temperature Structural Phase Transitions in GeV4S8
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... -
Low-temperature incommensurate magnetic structure study of magneto-dielectric...
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... -
Study of magnetic spiral in the room temperature multiferroic BiFeO3 - PbTiO3
BiFeO3 is a room temperature multiferroic, displaying both ferroelectric and antiferromagnetic (AFE) ordering. x-BiFeO3 - (1-x)-PbTiO3 is also multiferroic at room temperature...
