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... -
Effect of oxygen vacancies on the phonon dispersion of pyrochlores
The frustrated magnetism of pyrochlores makes them candidates for applications in magnetic cooling and scientific instrumentation, and the proposal that they can be used to... -
Characterization of local symmetry breaking in superconducting La2-xBaxCuO4 &...
The mechanism of high temperature superconductivity (HTSC) remains unresolved. Of particular interest is the origin of the mysterious pseudogap (PG, a partial gap in the... -
Pair distribution function analysis of stacking disorder in ice
Very recently, the metastable cubic ice phase was renamed to stacking-disordered ice (ice Isd) in order to emphasise the fact that this form of ice contains not only cubic... -
Superstructures in insulating and metallic lanthanum-doped sodium cobaltate
The thermoelectric properties of NaxCoO2 can be substantially improved by replacing Na ions by cations of higher valence. Our neutron diffraction studies on SXD for doping with... -
Structural Disorder in the Quantum Spin Liquid Candidate YbMgGaO4
Quantum spin liquids are novel magnetic states in which quantum entanglement suppresses conventional magnetic order. Understanding the effects that stabilise such states is an... -

Exotic finite-temperature collective excitations beyond standard Landau Fermi liquid framework exhibit anomalous temperature dependences in the transport and thermodynamic... -
Structural and magnetic neutron diffraction study of a novel frustrated syste...
Every new triangular lattice (TL) antiferromagnet attracts considerable attention since they usually display rich physics due to the inherent frustration and degenerate ground... -
Magnetic Fluctuations in BaCo2As2
ACo2As2 (A=Ba, Sr, Ca) are end members of Co doped Ba-122 family. Understanding the magnetic behavior of these end members can help us to understand the magnetic properties of... -
Tuning cycloidal ordering by epitaxial strain in BiFeO3 thin films
Owing to their promising applications, especially in spintronics, multiferroics have been at the fprefront of condensed matter research for a number of years. In these... -
Neutron scattering study on the phonon spectra of two-dimensional metal chalc...
Two dimensional (2D) metal chalcogenides are constituted by covalently/ionically bonded atomic layers that are held together via interlayer van der Waals (vdW) forces, and... -
Magnetic structure and multiferroicity in metal-formate perovskites
The family of guanadinium metal formates (M=Mn, Fe, Co, Ni, Cu) are isostructural with the perovskites and are therefore of interest for potential applications: in particular,... -
Magnetic structures of antiferromagnetic heavy fermion CeAuAl3 and CeCuAl3 co...
CeAuAl3 and CeCuAl3 compounds crystallize in the tetragonal I4mm, BaNiSn3-type and display interesting bulk properties. Here we propose to investigate the magnetic structures of... -
1D Spin-1/2 Chain Dispersion of Magnetoelectric CuO
We propose to measure the high energy magnetic dispersion of CuO. At high energies, CuO exhibits quasi-1D spin-1/2 chain magnetic behaviour. Our previous studies have revealed... -
Magnetic excitations of heavily electron overdoped BaFe0.8Ni1.2As2
We have devoted much efforts to investigating the doping evolution of the magnetic excitations in electron doped BaFe2-xNixAs2 (x=0-0.6). Spin excitations for x=0-0.6 have been... -
Correlation between crystalline and magnetic structures, and polarization in ...
TbMnO3 attracts special attention due to its large magnetoelectric coupling, polarization flop and ferro-paramagnetic phase transition, both induced by magnetic field. Despite... -
Superconductivity and critical spin fluctuations
In a successful recent experiment on IN5 (ILL), we have been able to show that in contrast to commonly accepted wisdom, the excitation gap in nearly optimally doped... -
Ex situ Study of glass formation from ion-exchanged Zeolite by INS
This proposal is a continuation of Rapid Access experiment RB170007 done on MARI in September 2016, as recommended by MARI beam scientists. This experiment was done to establish... -
Local structures and dynamics of new functional oxides
The melilite family are new xoide ion conductors with high mobility at low temperatures. Average structures suggest that the ability of the structure to accomodate high levels... -
Commensurate to incommensurate transition in triangular antiferromagnet PdCrO...
We propose to study an effect of uniaxial pressure on a magnetic structure of triangular antiferromagnet PdCrO2. The experiment will mark a technical milestone in development of...
