Magnetic excitations in honeycomb ruthenate Na2RuO3
Honeycomb magnets with strong spin-orbit coupling (SOC) are expect to produce exotic magnetic ground states as exemplified by d5 iridates with Jeff = 1/2 state. In d4 case, SOC... -
Origin of the magnetism in heavily electron-doped iron-selenide superconductor
Elucidating the nature of magnetism in a high temperature superconductor is important. Our previous neutron measurements at low temperature revealed a resonance mode at Q = (pi,... -

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... -
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... -
Excitation spectrum of isotope-enriched Sr2IrO4
Sr2IrO4 is an important material in condensed matter physics, having been discovered to host a novel Jeff=½ Mott insulating state.Yet while magnetic fluctuations play a crucial... -
Characterisation of Protons in Pyrochlore Electrocatalysts
This proposal is about understanding the atomic-scale structure of complex oxides that contain water or protons and that are used as electrocatalyts for water splitting. Such... -
Vibrational dynamics and proton sites in proton conducting perovskites
