High-Energy Solitary Magnons in CaFe2O4:
We have recently discovered solitary magnons in the classical magnet CaFe2O4 below 3 meV. in this experiment we propose to extend this to higher energy transfers to track how... -
Low Temperature Magnetic Properties of new Strontium(V) Ruthenate, SrRu2O6.
Layered strontium ruthenate materials are a prime example of how closely competing energy scales found in strongly correlated electron systems can give rise to a broad range of... -
Exotic phase coexistence in magnetic and superconducting LaFe(As1-xPx)(O1-yFy)
The proposed 1111 system whose structures are largely underinvestigated exhibits properties with a strong potential for novel properties that complement our knowledge of the... -
Order-disorder and phase transitions in the LiFeO2 cathode materials
Despite the importance of the LiFeO2 phases as cathode materials in lithium ion batteries, little is known about their crystal structures, except that they should be based on... -
Spin transitions in the hexagonal (6H) perovskites Ba3NdRu2O9
The hexagonal perovskites make up a large and technologically useful class of oxide materials, with applications as diverse as dielectric resonators for mobile phones and fuel... -
Insight into 4-hydroxyacetophenone polymorphs from single crystal neutron dif...
Beside the lattice energy, vibrational entropy has an important contribution to polymorph stability. We have developed a new method (NoMoRe - Normal Mode Refinement), which... -
Magnetic Phase Diagram of Geometrically Frustrated SrHo2O4
In SrHo2O4, the Ho3+ ions are arranged in a network of triangles and hexagons, and coupled with antiferromagnetic exchange interactions, this gives rise to geometric... -
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... -
Aza-crown-stabilized Alkali-Alkalide Systems: Solvent and metal effects on di...
We request 4 days on IRIS to investigate the diffusional and rotational dynamics of the alkalide forming, fully methylated aza-crown hexamethyl-hexacyclen (HMHC) in... -
Atomic structure of formamidinium lead iodide perovskite
New perovskite phases containing lead and halogens with a molecular cation are providing new options for materials in solar cells, giving unusually high efficiencies in... -
The single ion crystal field ground state of Yb3+ in Yb2Ir2O7
The rare earth iridates, R2Ir2O7 have been intensely studied in recent years due to the unique behaviour of the magnetism on the iridium sites; a consequence of competition... -
Inelastic Neutron Scattering study on Co-doped CeCu2Ge2
The AFM ground state of CeCu2Ge2 can be continuously suppressed by Co doping and NFL type behavior is seen around the critical concentration xc = 0.6. The electrical resistivity... -

Spin, charge and orbital ordering in CaMn4O8
Manganites oxides are of great interest in material sciences for the variety of physical properties they exhibit in connexion with possible long range spin, charge and orbital... -
Neutron diffraction and µSR investigation on YbPd
YbPd crystallizes in the cubic CsCl-type structure and reported to have magnetically ordered ground state with the mixed valence of the Yb ion. Further, it under goes through... -
Tuning the proton behaviour of a short strong intermolecular hydrogen bond as...
We have created very short intermolecular hydrogen bonds in benzoic acid "dimers" by co-crystallisation of these into molecular complexes with the proton sponge... -
In-Situ Quasi-Elastic Neutron Scattering Study of a Gas Loaded Indium-Carboxy...
We request 8 days on IRIS to study the diffusion of adsorbed H2 gas and C2-hydrocarbons molecules within a gated indium-based porous metal-organic framework (MOF) as a function... -

Complex structural modelling of amorphous [Au(SPh)]n and [M(1,2,4-triazole)2(...
Coordination polymers (CPs) with reversible phase changes between amorphous and crystalline states have recently become of interest for potential Phase-Change Memory... -
Superstructures in lithium cobaltate
The battery material LixCoO2 has recently been shown to have high thermopower comparable to NaxCoO2 at high x. In the case of NaxCoO2 we showed using neutron Laue diffraction on...
