Doping Dependence of the Resonant Spin Excitation in Ba1-xKxFe2As2
We recently observed a resonant spin excitation in Ba0.6K0.4Fe2As2, one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates that the... -
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... -
Inelastic neutron scattering study of spin gap formation in two forms of BaRuO3
Pseudogap phenomena, which are associated with the reduction in the density of states at EF, have been intensively investigated in HTSC, as well in heavy fermion systems through... -
High Energy Spin Fluctuations in BaFe1.9Ni0.1As2
There has been much research into the recently discovered iron based superconductors, but so far only the magnetic excitations at low energy have been investigated. We propose... -
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... -
Magnetic ground state of the candidate quantum ice material Pr2Sn2O7
Quantum spin ice is a novel form of matter in which the spins remain dynamic even at absolute zero due to quantum fluctuations. The requirements on the single-ion wavefunction... -
Neutron scattering and muSR studies of magnetic phenomena in YFe2Al10: case s...
In strongly correlated electron systems, the proximity to magnetic ordering has been of special interest. Magnetism in this class of systems is often suppressed by the Kondo... -
Investigation of the spin dynamics of Shastry-Sutherland phase in Ce2-xPd2+yI...
The Shastry-Sutherland lattice (SSL) can be described as a 2D square lattice built up from a network of dimers disposed orthogonally and has been observed in SrCu2(BO2)3.... -
Spin excitations of detwinned BaFe2As2
Although spin excitations in BaFe2As2 are thought spin-wave excitations and the excitation will locate at antiferromagnetic vector (1 0) only for a detwinned sample, the real... -

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... -
Lattice dynamics study of filled-skutterudite compounds: RPt4Ge12 (R=Ba, La a...
The appearance of non-dispersive Einstein (¿rattling¿) modes, known as the phonon-glass paradigm in filled-skutterudite compounds, has been postulated as an origin of the high... -
Magnetic field induced phase transition in two dimensional triangular lattice...
We propose to conduct an inelastic scattering study on NaVS2 and NaVSe2 in zero magnetic field on the MARI spectrometer. These compounds form triangular lattices which are... -

We wish to measure the partial dynamical structure factors and the partial vibrational density of states (VDOS) for the archetypal network forming glass GeSe2 by using the... -
Search for magnetic fluctuations and a spin resonance in FeSe intercalated wi...
Very recently, bulk superconductivity has been found at Tc = 43 K in the layered compound FeSe intercalated with Li ions and amide and ammonia molecular groups. We propose to... -
Crystal field and magnetic excitations of the non-centrosymmetric heavy-fermi...
Several non-centrosymmetric heavy-fermion compounds have been reported to exhibit unconventional superconductivity (SC). For example, both CeRhSi3 and CeIrSi3 order... -
Inelastic neutron scattering investigations on CeFeAs1-xPxO compounds
Recently, it has been reported that CeFeAsO belongs to the orthorhombic structure where both Fe and Ce orders antiferromagnetically around 140K and 4K, respectively, whereas Ce... -
Inelastic Neutron Scattering study on new tetragonal compound Ce2PdGe3
Cerium-based Kondo lattice compounds have received great attention, owing mostly to the variety of exotic ground states that they exhibit (e.g., unconventional... -
Determination of the on-top vibrational mode of the surface hydride in PdH.
Finely divided supported palladium particles are used as catalysts in many technical processes. Using MAPS we have recently investigated the interaction of hydrogen with the...
