Magnetic interactions in the room-temperature skyrmion material Co8Zn8Mn4
We propose an investigation of the spin-waves in the recently discovered room-temperature skyrmion material Co8Zn8Mn4. The ground state of Co8Zn8Mn4 is a very long wavelength... -
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... -
Excitation Spectrum of the Topological Spin Order in SrFeO3
Spin dynamics in multi-q noncoplanar ordered structures (e.g. skyrmion lattices) is an active topic of research. The cubic perovskite SrFeO3 has a variety of multiple-q magnetic... -
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... -
Investigation of magnon dynamics of rare-earth garnet Ho3Fe5O12
Rare-earth Iron garnets (RE3Fe5O12) have been in the focus of active research for the last five decades due to their fascinating properties, such as large magnetostriction,... -
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... -
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... -
Exchange interactions and spin gap in Cu2PO4OH
The mineral Libethenite, Cu2PO4OH, is an ideal system in which to study low dimensional quantum magnetism. Its magnetic behaviour is complex but is related to systems with...
