High-energy magnetic excitations in FeSe
FeSe (Tc = 9 K) being structurally the simplest iron based superconductor shows some exotic properties. For instance, it only undergoes a tetragonal-to-orthorhombic structural... -
Phase stability and thermal conductivity in perovskite zirconates
Perovskite zirconates have been suggested as potential next generation thermal barrier materials. SrZrO3 is particularly promising as it has an extremely low thermal... -

Vibrational dynamics and proton sites in proton conducting perovskites
Solid oxide fuel cells (SOFCs) operating at intermediate temperatures are a promising clean energy technology. At the heart of these devices is a proton conducting oxide... -
Neutron scattering studies of hydrogen rotational transitions in Ni-MOF-74
We propose to use MARI to look at the full rotational spectrum of H2 in Ni-MOF-74 obtaining the full momentum distribution for H2 only at the Ni metal site and one with partial... -
Inelastic neutron scattering of non-Fermi-liquid behaviour in Ce2PdIn8
For non-Fermi liquid compounds, the dynamical susceptibility, as determined from inelastic neutron scattering, is particularly interesting as it exhibits universal energy... -
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... -
Magnetic excitations in the half-metallic shandite Co3Sn2S2
Co3Sn2S2 is a metallic ferromagnet with Tc = 177 K, which crystallizes in a shandite-type structure. Below the Curie temperature its electronic structure forms a half-metal... -
Crystal Electric Field (CEF) Effect in CeIr3Ge7 and YbIr3Ge7
We recently discovered new members of the stoichiometric 1-3-7 family of crystals including YbRh3Si7, YbIr3Ge7, CeIr3Ge7, and YbIr3Si7, whose magnetic and transport properties... -
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... -

Novel state of matter in the site-ordered double perovskites Ba2YWO6
In solids, spins and orbitals are usually not coupled to each other. This may be not true any more in the rocksalt ordered double perovskites having spin-orbit coupling.... -
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... -

Na-Dynamics in Solid Ionic Conductors: 11Al2O3-Na2O and Na2Ti3O7
We would measure vibrational spectra as well as quasielastic neutron scattering (QENS) spectra for beta- alumina (11Al2O3-Na2O) and Na2Ti3O7. The measurement of phonon spectra... -
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... -
Unveiling molecular and collective magnetism in the coupled trimer spin syste...
When isolated spin clusters are weakly coupled to each other, zero-dimensional quantum and three-dimensional collective magnetism concomitantly occur. This is envisioned in the... -
Ligand-field characterization and U-Pt bonding in uranium-based heterometalli...
We propose to investigate the magnetic excitation spectra of tetravalent uranium ions in two isostructural, one-dimesional chains made up by aligned UM2 units, with M = Pt and... -
