The microscopic origin of the zigzag magnetic ground state in a honeycomb lattice of the quasi-2D antiferromagnet Na2Co2TeO6 is debatable. The zigzag phase may occur due to (i)...

This proposal was submitted on MERLIN (RB1010206) and beam time was allocated on MARI. We have carried out low energy measurements on MARI and found a clear evidence of the spin...

The strontium iridate Sr2IrO4 has recently received a special attention because of its closeresemblance to undoped high-Tc cuprate in terms of structural, electronic, and...

Oxide ion conductors are researched as electrolytes in solid oxide fuel cells. Yttria-stabilized zirconia is the currently used electrolyte in SOFCs, leading to high operating...

We propouse the study of crystal-field or vibron excitations along the series RAgxCu1-xAl3 (R=Ce and La, 0<x<1), where we expect to studing two main aspects. The first one...

SMMs have received much attention owing to their quantum tunneling and slow relaxation of the magnetization. This has led to an intense activity by synthetic chemists to...

SrTb2O4 belongs to the family of rare-earth RE strontium oxides, SrRE2O4. These compounds, consisting of hexagons and triangles, are affected by geometrical frustration and...

Crystals of the filled skutterudite PrFe4Sb12 with the 73~87% Pr-site filling fractions prepared under ambient pressure show some magnetic ordering around 5 K and their...

A series of recent incoherent inelastic neutron scattering (INS) experiments on low-temperature D2+H2 and Ne+H2 mixtures have revealed pronounced deviations from the Gaussian...

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...

In a magnetic Weyl semimetal (WSM) with broken time-reversal symmetry, large intrinsic anomalous Hall effect is expected if the Weyl nodes are close to Fermi energy, which...

: Recently the Kondo insulators CeT2Al10 (T=Fe, Ru and Os) have attracted considerable attention. T=Ru and Os order AFM below 29 K, while T=Fe remains paramagnetic. At low...

Recently we have synthesized and investigated three new ternary intermetallic compounds PrTSi3 (T = Ir, Rh and Ru) which form in BaNiSn3-type tetragonal structure (space group...

Recently it has been reported that YbAl3C3 undergoes an antiferromagnetic quadrupolar ordering transition at 80 K, Further study by Ochiai et al. revealed that the transition at...

Ba4Mn3O10 and Sr4Mn3O10 crystallize in an orthorhombic crystal structure consisting of corrugated layers containing Mn3O12 polydedra. The magnetic susceptibility of the...

In contrast to the extensively verified Weyl semimetals with broken inversion symmetry, magnetic Weyl semimetals, which break time reversal symmetry, were only theoretically...

We propose to study the magnetic excitation spectrum of Na2IrO3 with inelastic neutron scattering. Na2IrO3 is a promising candidate to realize Kitaev interaction. By mapping out...

The present proposal is part of a larger EPSRC project advancing the vibrational spectroscopy of silicate glasses. The project involves the techniques of IR and Raman...

The method of Se isotope substitution with inelastic neutron scattering will be used to measure the partial VDOS for As2Se3 glass. This is a prototypical network forming...

Our recent inelastic neutron scattering (INS) study using MARI clearly reveals the presence of a sharp inelastic excitation near 8 meV and 11 meV in CeT2Al10 (T=Ru and Os)...
