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... -
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... -
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,... -
Temperature dependence of the high-energy spin excitations in the newly disco...
Understanding the magnetism in iron pnictides is one of the most important steps to reveal the mechanism of superconductivity in these novel materials. In the extensively...
