Magnetic excitations in CrB2
CrB2, like MnB2, are transition metal diborides that have magnetically ordered ground states. Preliminary neutron (TAS) work and in house lab indicated that the dispersion has... -

Inelastic magnetic scattering in CePd3
CePd3 is a classic intermediate valence (IV) system. In MAPS experiment 620167 we obtained an important qualitative result for CePd3, namely that the Kondo-like scattering... -
Solvent Segregation in Phase-Separated Li-NH3-MeNH2
We request 2 days on MAPS (or 3 days on MARI) to determine the extent of solvent segregation in a liquid-liquid phase-separated metal-amine: The Li-NH3-MeNH2 system. Recently we... -
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... -
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... -
Effect of electron doping on the magnetic dynamics of the d^4 Mott insulator ...
Oxides containing heavy transition-metal ions with four d electrons (d^4) surrounded by an octahedron of oxygen ions have recently been predicted to display a novel type of... -
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].... -
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.... -
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... -
Spin dynamics in the zig-zag ladder beta-CaCr2O4
We propose to investigate the spin dynamics in the frustrated antiferromagnet beta-CaCr2O4. Its structure consist in one dimensional chains of Cr+3 forming the legs of zig-zag... -
Orientational and conformational disorder in a halogen-ethane compound
The translational and orientational disorder of some liquids can be frozen if they are cooled down quick enough, giving rise to a Structural Glass (SG). But for some molecular... -
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... -
Paramagnetic excitations in BaFe2As2 at high temperature
One fundamental issue in the iron-based superconductors is whether the conventional local moment Heisenberg model is sufficient to describe magnetism in these materials, or... -
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...
