Full reciprocal space imaging of the acoustic phonons in MgV2O4:
The proposal requests time to obtain a full mapping of the low-energy acoustic phonons. We have measured an acoustic phonon anomaly associated with the structural transition and... -
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... -
Spin wave excitations in the 2D honeycomb ferromagnets
Graphene is the single layer of honeycomb-shaped carbon network, for which 2010 Nobel Prize in Physics was awarded thanks to its novel electronic properties. One of such... -
Search for magnon-phonon coupling effect in metallic triangular antiferromagn...
Spin dynamics of non-collinear magnetic structures can exhibit the rare phenomena which go beyond the linear spin wave theory. Our previous studies on non-collinear...
