We propose to investigate the highly one-dimensional (1D) S=1/2 Heisenberg antiferromagnet (NO)[Cu(NO3)3] which is a potential realization of the Nersesyan-Tsvelik model. The... -
Spin gap and possible spin-dimer formation in Ce(Os1-xFex)2Al10 (X=0 to 1)
Our neutron study using MARI/MERLIN on Ce(Ru1-xFex) 2Al10 reveals very interesting magnetic excitations and a manuscript is ready to submit to PRB. In x=0 (TN=27 K) a... -
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... -
Spin excitations in La2CoO4
We will use MAPS to measure the complete spin excitation spectrum of the quasi-two-dimensional S=3/2 antiferromagnet La2CoO4. The measurement is motivated by recent observations... -

Temperature dependence on mangetic excitations from the high Tc cuprate BSCCO
We plan to continue inelastic neutron scattering measurements on the high Tc cuprate superconductor BSCCO with optimum doping. In the proposed experiment, we will have about 40... -
Magnetic excitations in the S=1/2 ferromagnetic semiconductor Lu2V2O7
Lu2V2O7 is a rare example of an S=1/2 pyrochlore. The fact that it is a ferromagnet with Tc=70 K belies the fact that it has some truly remarkable properties. These include the... -
Spin excitations in the superconducting FeTe0.6Se0.4
The FeTe1-xSex series exhibits superconductivity over a broad range of doping. Previously we have made extensive neutron scattering measurements on superconducting x = 0.49 and... -
Neutron spectroscopy of a novel family of Ln2 dimers
Molecular nanomagnets containing 4f ions are attracting an increasing interest because of their large magnetic anisotropy and slow relaxation of magnetization originating from... -
Mapping magnetic excitations in insulating phase of NaFe0.52Cu0.48As
Magnetism is believed to be linked to superconductivity in cuprates and iron pnictides. However while the parent compounds of cuprates are Mott insulators, the parent compounds... -
Paramagnetic excitations in NaFe0.53Cu0.47As
NaFe0.53Cu0.47As is an antiferromagnetic Mott insulator which connects unconventional superconductivity and Mott physics. The magnetic fluctuations in the ordered state has been... -
Observation of intermediates on a transfer hydrogenation catalyst
The design and development of novel catalysts for chemical synthesis is incredibly important from both academic and industrial perspectives. Approximately 90 % of all commercial... -
Spin excitations in the paramagnetic phase of a charge-ordered bilayered mang...
In a previous experiment we measured the spin wave spectrum of the half-doped bilayer manganite Pr(Ca,Sr)2Mn2O7 in its spin, charge and orbital ordered phase. The data, which... -
Magnetic excitation in triangular latticce antiferromagnet alpha-CaCr2O4
The triangular Heisenberg antiferromagnet is the classic example of the frustrated magnet, here the ground state forms a non-collinear 120° structure. A number of different... -
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... -
Can we use the H-H stretch of adsorbed dihydrogen to characterise materials?
The use of the J 0-to-1 rotational transition of dihydrogen has been extensively used to characterise the state if hydrogen in and on materials. The disadvantage of studying the... -
