High-energy excitations in charge and orbital ordered La0.5Sr1.5MnO4
The colossal magnetoresistance effect in manganites arises from a competition between delocalisation, which favours a ferromagnetic metallic phase, and localisation of electons... -
Study of phonon density of states in PGEC titanate thermoelectrics
To understand the thermal conductivity suppression within PGEC titanate oxide thermoelectrics we hope to complement theoretical calculations performed on several perovskites... -
Magnetic Excitations of Isolated and Pairs of Co Ions and in MgO
The magnetic excitations will be studied in a powdered sample of 3% CoO in 97% MgO in order to to study the excitations of isolated Co ions and of isolated pairs of Co ions.... -
Excitations in an orbitally dimerized spin S=1 honeycomb antiferromagnet
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... -
Inelastic neutron scattering investigations to study Ru-trimer and molecular ...
The orthorhombic compound Ba4Ru3O10 having Ru3O12 timers coupled via corner-shared oxygens in the crystal structure exhibits very interesting magnetic and transport properties.... -
The relationship between the pseudogap and magnetic excitations in La2-xSrxCuO4
This proposal is part of an ongoing project to relate the magnetic excitations to other electronic properties of the cuprate superconductors. We have recently proposed that the... -
How does a catalyst promoter affect the degree of hydrogen retention of iron-...
We have recently used INS to determine how a hydrogen pre-treatment stage of an iron based Fischer-Tropsch catalyst may modify catalytic performance. That work established how... -
INS as a dual-probe of giant magnetic anisotropy and vibrational density of s...
Monometallic complexes of paramagnetic transition metal or lanthanide metal ions have found to exhibit single-molecule magnet (SMM) behaviour with an appreciably enhanced... -
High-Energy dynamics and search for a continuum in CaFe2O4
We propose to investigate the high-energy (above 10 meV) excitations using either the MERLIN or MAPS chopper instruments. CaFe2O4 is interesting for several reasons. First, it... -
Investigation of nonmagnetic degenerated ground state in a cubic 4f2 system P...
Praseodymium-based cubic compounds with a 4f2 configuration have attracted much attention. In case the crystalline electric field ground state is a nonmagnetic doublet, the... -
Probing the origin of low thermal conductivity in thermoelectric materials
Thermoelectric materials are increasingly attracting attention due to their potential for use in devices for waste heat energy recovery. Bismuth copper oxychalcogenides have... -
Alkali ions dependent collective excitations in borate glasses
Recently, it has been suggested that the First Sharp Diffraction Peak (FSDP) in glasses arises from a quasi-periodicity of void spaces in the structure, that plays the role of... -
Probing the mechanism of thermoelectric enhancement in Kondo insulator YbB12 ...
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... -

Resolving the crystal field scheme for Dy3+ in DyNiAl4
The intermetallic series RNiAl4 (R = rare earth) exhibit interesting low temperature magnetic behaviour including a variety of (in)commensurate magnetic phases and metamagnetic...
