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... -
INS of Ln(trensal-thiphene)
We have synthesised the series of lanthanide complexes Ln(trensal-thiophene), where Ln = Er, Dy, Yb and H3trensal = 2,2,2-tris(salicylideneimino)trimethylamine. These... -
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... -
Topological magnons in Cu2OSeO3
Recently, it was predicted topological nature of the magnetic excitations of Cu2OSeO3. It turned out that the system belongs to the class of topologically non-trivial magnets... -
Spin waves in the single layer half doped manganite Pr0.5Ca1.5MnO4
We propose to measure the spin wave dispersion and intensities throughout the Brillouin zone of the single layer half-doped manganite Pr0.5Ca1.5MnO4, whose ground state has the... -
Evolve of the Spin Waves in Rb0.8Fe1.6Se2 at High Temperature
The newly discovered AxFe2-ySe2 (A=K,Rb,Cs) compounds have attracted great interests because of their parent compounds are insulators instead of being metallic [2-6].... -
Inelastic magnetic excitations in NaFe0.95Co0.05As (Tc~17 K)
Though NaFeAs shares the same crystallographic structure with LiFeAs, there are many different aspects between them. We would like to compare the magnetic excitation in it with... -
Doping-induced energy gap in a quantum spin chain
SrCuO2 is a prototypical S = 1/2 antiferromagnetic (AF) Heisenberg 1D spin chain system. High-resolution neutron scattering studies has already successfully revealed the gapless... -
Magnetic excitations in mesoporous hematite
We have recently prepared mesoporous forms of various metals oxides. In some cases the imposition of a mesostructure changes other properties of the material significantly. One... -
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... -
Molecular and framework dynamics in CH3NH3PbCl3
We propose to use MARI to measure the molecular and framework dynamics in CH3NH3PbCl3 which has become of interest in the context of efficient photovoltaics. CH3NH3PbCl3 is... -
Soft Modes in the Ferroelectric Semiconductor SbSI
Antimony sulfo-iodide (SbSI) exhibits strongly-coupled photoconductive, semiconducting, and ferroelectric properties. Until the discovery of the lead-oxide ferroelectric relaxor... -

The Evolution of the Antiferromagnetic Order with Hole Doping of La2-xSrxCoO4.
Many believe that the magnetic excitations of cuprate high temperature superconductors play an important role in the material's superconductivity. Understanding the magnetic... -
Search for magnetic correlations in Fe phosphide superconductors
We propose to use inelastic neutron scattering to search for the existence of spin fluctuations in two iron phosphide superconductors, LaFePO and Sr2ScFePO3. The objective is to... -

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... -
Understanding the ground state wavefunction in PrPtAl and YbNiSn
The proposal addreses the compounds PrPtAl and YbNiSn. Both systems are canted ferromagnets with both materials undergoing moment reorientation transitions as a function of... -
Inelastic neutron scattering study of exchange disorder in CaFe2O4 and CaFe1....
We would like to investigate polycrystalline CaFe2O4 which undergoes two magnetic transitions to a B phase below 190 K and to a A phase below 160 K. Both phases coexist in a... -
Magnetic fluctuations and ordering in two-dimensional and ferromagnetic Cr2Ge...
The proposal requests time to measure the magnetic fluctuations in a 2 dimensional ferromagnet where the dimensionality is set by weak van der Waals forces. We have previously...
