Spin anisotropy of Seff=1/2 triangular rare-earth based antiferromagnets
In quantum magnetism significant efforts have been devoted to the search for new quantum states. In particular the Quantum Spin Liquid (QSL) state on the triangular lattice has... -
Dynamical Transitions in the Ogg Glasses
We request 4 days on IRIS to study the temperature dependance of the structural dynamics in amorphous sodium-ammonia (Na-NH3). This will be the first investigation of the... -
HIGH RESOLUTION NEUTRON DIFFRACTION STUDIES ON NEW POLYMORPHS OF MAGENSIUM TE...
The development of high energy density and high efficiency hydrogen storage materials is widely considered to be one of the most challenging barriers to the adoption of fuel... -
Uniaxial pressure induced spin-density wave order in CeAuSb2
We propose to apply uniaxial strain to induce a spin-density wave (SDW) modulation in CeAuSb2. Neutron diffraction measurements show this system has a tendency to order along... -
Copy of: Structural and Magnetic Studies of Mixed-Valence Iron Silicates
We propose to study the temperature evolution of the spontaneous strain, crystal and magnetic structure of the charge ordered, mixed valence iron silicate ilvaite. In addition,... -

High resolution neutron powder diffraction on Ni-Mn-Sn based shape memory all...
The composition Ni2.04Mn1.4Sn0.56 belongs to the group of metamagnetic shape memory alloys and it shows multiple magnetic phases as a function of temperature. In a recent muon... -
Investigation of a new three-dimensional frustrated quantum magnet
Interesting behaviour in Heisenberg spin systems originates from networks of triangles or tetrahedra, where spins interact via antiferromagnetic interactions. In 3D there are... -
PNR of Magnetic Order in Delta-Doped Topological Insulators
We aim at studying proximity effects between a ferromagnetic thin film (either metallic or insulating) and a topological insulator (either undoped, or magnetically homogeneously... -
Cation reorientation dynamics in a metal formate perovskite
Hybrid metal-organic perovskites are promising functional materials, but the complex interactions between organic cations and the framework surrounding them are difficult to... -
Determination of the on-top vibrational mode of the surface hydride in PdH.
Finely divided supported palladium particles are used as catalysts in many technical processes. Using MAPS we have recently investigated the interaction of hydrogen with the... -
Magnetic excitations in a candidate magnetic XY analogue of graphene
This proposal is part of our research programme to explore the experimental manifestation of topological properties of magnetic excitations. The honeycomb ferromagnet is... -
Can we use the H-H stretch of adsorbed dihydrogen to characterise materials?
The use of the J 0-to-1 rotational transition of dihydrogen has been extensively used to characterise the state if hydrogen in and on materials. The disadvantage of studying the... -
Does Na2Co2TeO6 realize the Kitaev model?
Preliminary data on the spin excitation spectrum of the honeycomb lattice compound Na2Co2TeO6 are consistent with the existence of Kitaev interactions, as was recently proposed... -
Single-Crystal Neutron Diffraction Study on [U(C5Me5)2(H)(mu¿H)]2
To our knowledge, the length of the U¿H single bond has never been accurately measured, at least not in a molecular compound by single-crystal neutron diffraction. We currently... -
Neutron scattering study of a triangular-lattice NaYbO2: a quantum spin liqui...
The Quantum spin liquid (QSL) state continues to fascinate the condensed matter community. This is because the spins in a QSL are highly entangled and fluctuate strongly down to... -
Structure and magnetic order in chemically modified schafarzikites
Schafarzikite minerals are structurally interesting in having 1-D chains of edge-linked transition metal octahedra. This experiment aims to determine the cause of the... -
Proton diffusion in lithium imide: a quasi-elastic neutron scattering study
Li_2NH has been recently considered for H_2 storage applications. However, its low-T crystal structure is still controversial, with at least 6 options compatible with the... -
Phonon Dispersion in the Organic Ferroelectric Croconic Acid
Organic ferroelectrics are important materials because of their technological applications in low-cost non-volatile memory elements. Single-crystal croconic acid (C5O5H2) is the...
