High-energy excitations in a spin orbital liquid on the diamond lattice
This proposal is part of our research programme on spin and orbital order in frustrated systems. The spinel FeSc2S4 realises an exotic ¿spin-orbital liquid¿ with no magnetic or... -
Neutron spectroscopy in mononuclear Ni(II) complexes
Mononuclear Ni(II) complexes can be designed to behave as two-level systems and thus play the role of qbits with eventually large coherence time. The objective of this proposal... -
Simultaneous Raman and INS studies of high energy excitations in C70
The vibrational spectrum of C70 has been investigated by many techniques since it became available in significcant quantities. Previous INS spectra were recorded with small... -
High precision measurements of the spin wave dispersion in Yttrium Iron Garnet
Yttrium Iron Garnet (YIG) is a material with extremely wide ranging applications, having the narrowest ferromagnetic resonance linewidth of any known material. Despite decades... -
Is magnetic frustration behind the tetragonal-to-orthorhombic transition in t...
It has been argued that the tetragonal-to-orthorhombic structural transition found in all the parent phases of the Fe-pnictide superconductors is driven by frustration, and... -
Study of a spin gap and CEF excitations in the caged compounds CeT2Al10 (T=Fe...
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... -

Is there electronic nematic order in Fe pnictides?
The concept of an electronic nematic, in which the electronic wavefunctions have different symmetry to the crystal structure, has been proposed to explain several unusual... -
Magnon diffusion in the spin Seebeck material magnetite
The spin Seebeck effect is a newly discovered phenomenon that if harnessed, could result in a significant improvement of the efficiency of thermoelectric energy generators. SSE... -
Magnetic Excitations in Chromium
Chromium is unique amongst the d-band elemental metals in that it has a spin density wave ground state. The spin density wave is caused by Fermi surface nesting between electron... -
Magnetic excitations in single-crystals of LaFeAsO
We aim to determine the magnetic excitation spectrum in single-crystals of the parent LaFeAsO compound and thereby address some basic issues concerning the nature of the... -
Spin excitations in LiFeAs, a stoichiometric ferropnictide superconductor at ...
We propose to measure the powder-averaged spin excitation spectrum of LiFeAs, a new member of the ferropnictide family of superconductors. This compound is special because it is... -
Coating dependance of the phonon density of states in LiFePO4 nanoparticles
LiFePO4 (LFP) is a commercially used Li ion battery material for high power applications. Particle shape and surface play an important role in the Li diffusion and thus the... -
Spin Waves in the Parent Compound of the Superconductor FeSexTe1-x (x=0)
The iron containing superconducting system FeSexTe1-x has a similar phase diagram to the cuprate superconductors, in that a non-superconducting antiferromagnetic parent compound...
