Anomalous lattice dynamics of the elemental superconductor niobium
Phonon lifetimes in BCS superconductors provide information on the details of the electron-phonon coupling mechanism. In 2008 high-resolution neutron inelastic scattering... -
Magnetic dispersion and anisotropy in HoFeO3 with spin reorientations
HoFeO3 have two magnetic ions, Ho3+ and Fe3+, and three types of magnetic interactions between these two ions. These three interactions play different roles at different... -
Magnetic excitations in a candidate magnetic XY analogue of graphene
This proposal is part of our research programme to explore the experimental manifestation of topological properties of magnetic excitations. The honeycomb ferromagnet is... -
Magnetic excitations in single crystal BaFe2Se3
In this proposal, we propose to investigate the spin dynamics in the complex material BaFe2Se3. This material presents low dimensional magnetisme below 250K, combined with... -
Magnetic excitations in a rare earth Kitaev material
Among the intense research on quantum spin liquid states, the Kitaev model has attracted great attention. Compounds consist of honeycomb layers with strong spin-orbit coupling,... -
In search for magnon-magnon/phonon coupling in metallic triangular antiferrom...
Recent theories and experiments on two-dimensional triangular lattice antiferromagnet show that the spin dynamics of these system exhibit the rare phenomena due to high-order... -
Examining the magnon-magnon/phonon coupling in a new multiferroictwo-dimensio...
Non-collinear two-dimensional triangular antiferromagnets (2D TLAF) are currently an area of much active research due to their unique magnetic properties which lead to... -
Exotic spin excitations in a quasi one-dimensional anisotropic Heisenberg magnet
Very recently, string states have been identified for the first time in antiferromagnetic Heisenberg-Ising chain SrCo2V2O8 in longitudinal magnetic fields using high-resolution...
