Dirac Nodal Line Magnons in a Stacked Honeycomb Magnet
On the basis of exchange couplings obtained from early inelastic neutron measurements, we conjecture that the stacked honeycomb magnet FeTiO3 contains Dirac nodal lines in the... -
Spinon Confinement and Longitudinal Interchain modes in Yb2Pt2Pb
The f-electron metal Yb2Pt2Pb is best thought of as a one dimensional (1D) quantum spin chain system, despite the fact that the magnetic moments are large and anisotropic with... -
Detecting an entanglement transition in a quantum magnet
Justification: We'd like to apply for three days Director’s Discretionary time on WISH to continue the experiment on measures of quantum entanglement in a model 1D magnet. This... -
Quantum and thermal critical scaling in XY-dipolar antiferromagnet LiErF4
We have established the material LiErF4 as a dipolar antiferromagnet with planar anisotropy, exhibiting both classical and quantum phase transitions. Where, thermal transition... -
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... -
Magnetic Excitations on the Frustrated Triangular Lattice of UAu2
Nature abhors disorder and degeneracy at low temperature. Designing materials that confront this requirement can therefore lead to new states in which the degeneracy is lifted.... -
Phonon measurements of the incommensurate phase transition in Åkermanite
The proposal is to measure the inelastic scattering from a single crystal of Åkermanite on cooling towards and through the incommensurate phase transition at 358 K. There are... -
Resonant Spin Excitation in Single Crystal of Ba0.3K0.7Fe2As2
We recently observed a resonant spin excitation in Ba1-xKxFe2As2 (x=0.4), one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates... -
Detecting quantum critical fluctuations in the distorted kagome Kondo compoun...
Geometrically frustrated spin systems have been studied extensively for decades because of many intriguing phenomena, exemplified by the non-magnetic quantum disordered states.... -
Latex - structure in binary mixtures - studies of crystallisation and stability
Recent experiments on SANS2D have indicated that small colloidal particles can act as macroions that screen the charged interactions of larger particles. This can cause changes... -
Mapping the magnon spectra in the skyrmion phase of MnSi
In cubic B20 structures, skyrmions, topologically-protected three-dimensional spin textures, arise from competition of the ferromagnetic exchange interaction and the... -
Investigation of a frustrated quantum magnet with novel interaction scheme
SrCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions that are coupled into network of isolated triangles,a highly frustrated hyperkagome lattice consisting of... -
Unravelling spin fluctuation components in a stripe-ordered cuprate
In previous experiments at ILL we observed a gap in the magnetic excitation spectrum of the stripe-ordered superconductor (La,Nd)2-xSrxCuO4, x=0.12. We observed a spin gap of... -
Investigating Modulation in Molecular Materials:
Valuable information is lost when the focus is put only on the average unit cell and not the long-range order of the whole crystal. Determination of the long-range ordering can... -
Investigation of the relevant thermodynamic parameters for the production of ...
With fantastic flux gains over its liquid conterpart, a solid methane moderator is essential to the newly built Second Target Station at ISIS. Unfortunately, it is notoriously... -
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... -

Proton diffusion in zirconate perovskites investigated by QENS
The growth in both global demand for energy and fossil-fuel related environmental issues drive research on alternative fuel sources. Solid oxide fuel cells, which can operate on... -
Evidence for long-range order in HoTbTi2O7
Evidence of long-range order has been observed in the diffuse neutron scattering data for a single crystal of HoTbTi2O7.A spin ice like pattern and pinch points coexist with the... -
Nearly ferromagnetic fluctuations in CeRhSi3? A high resolution study at lo...
