Magnetic excitation spectrum near incipient SDW order in Nb1-xFe2+x
Our previous neutron diffraction on C14 Laves phase compounds Nb1-xFe2+x revealed thata spin-density-wave (SDW) is masking an underlying ferromagnetic (FM) quantum critical... -
Low energy magnetic excitations on a new triangular-lattice antiferromagnet
Given the controversy about the magnetic ground state of the recently well studied triangular-lattice antiferromagnet (TLA) YbMgGaO4 due to Mg2+/Ga3+ disorder, we have... -
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,... -
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,... -
Spin-orbit transitions of Co3+ in LaCoO3
In our first measurement of the high energy spectrum of LaCoO3 we observed a signal which is a promising candidate for an electronic transition from the low spin ground state of... -
