The intermetallic series RNiAl4 (R = rare earth) exhibit interesting low temperature magnetic behaviour including a variety of (in)commensurate magnetic phases and metamagnetic...

New electronic phases often emerge in the proximity of a quantum critical point (QCP) - that is the point where the transition temperature of a collective phase transition is...

We propose to study the evolution of the spectral features in the dynamical magnetic response in series Yb_{1-x}Tm_{x}B_{12} (x=0.15, 0.6, 0.8). Tm doping results in non-trivial...

Thermoelectric materials are increasingly attracting attention due to their potential for use in devices for waste heat energy recovery. Bismuth copper oxychalcogenides have...

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...

The Dzyaloshinskii-Moriya interaction is thought to be responsible for the stabilization of weak ferromagnetism or magnetic spiral states in a number of diverse systems. An...

Single-molecule magnets (SMM) exhibiting slow magnetic relaxation have attracted increasing interest, both from a fundamental point of view, and for the potential practical...

Due to the tunable interplay between magnetism and superconductivity the CenTmIn3n+2m (n, m = 1, 2; T = Co, Ir, Rh, Pd, Pt) family of heavy fermion compounds has been attractive...

We propose to use MERLIN to measure INS from commercial zeolite catalyst samples extracted from a reactor in which they have been exposed to dimethylether for different lengths...

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...

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...

We have investigated the magnetic structure and crystal field excitations (CEF) of CeT2Al10 (T=Os and Ru). The observed magnetic moment along the c-axis does not agree with that...

As part of a UK Catalysis Hub initiative in Catalyst Design involving a team of academic and industrial researchers, the methanol-to-gasoline reaction over zeolite catalysts is...

The spin excitations in superconducting LiFeAs have been found evolved from incommensurate peaks to commensurate peak at low energy. But the spin resonance is still not clear in...

Ru4+ ions in Li2RuO3 are on a bipartite lattice and have an orbital degeneracy. The four electrons of the magnetic Ru4+ ions in the threefold-orbitally degenerate t2g manifold...

A strong Q-dependence of the magnetic response at characteristic energy of EK~kBTK (TK is a Kondo temperature) has been observed in recent inelastic neutron scattering studies...

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...

We clearly observed incommensurate (IC) magnetic excitation in KFe2As2 above Tc with Ei=80 mev on ARCS at ORNL. Though we got beam time at LET, we wish to see how the IC changes...

Cerium-based Kondo lattice compounds have received great attention, owing mostly to the variety of exotic ground states that they exhibit (e.g., unconventional...

Organic ferroelectrics are important materials because of their technological applications in low-cost non-volatile memory elements. Single-crystal croconic acid (C5O5H2) is the...
