Dirac Nodal Line Magnons in a Stacked Honeycomb Magnet
On the basis of exchange couplings obtained from early inelastic neutron measurements, we conjecture that the stacked honeycomb magnet FeTiO3 contains Dirac nodal lines in the... -
Determining Microscopic Origins of the Thermal Hall Effect in Tb2Ti2O7
Studies of thermal Hall effects in insulating materials ascribe its microscopic origins to charge-neutral bosonic carriers generated by non-zero Berry curvature in the... -
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... -
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...
