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... -
Phonon Anomalies in Charge-Density-Wave Ordered La2-xSrxCuO4
It has been known for some time that the CuO bond-stretching phonon in the high-temperature superconductor La2-xSrxCuO4 (LSCO) exhibits anomalies is its dispersion and damping.... -

Roles of magnetic anisotropy and inter site exchange interactions in the temp...
NdMnO3 exhibits A-type antiferromagnetism with TN =73 K. At 15 K, Nd sublattice orders with a (0, -Fy, 0) type ferromagnetic arrangement. Mn spin reorientation from (Ax, Fy, 0)... -
Lattice dynamics in magnetoelectric HoMnO3
The manipulation of magnetic properties electronically is of great importance in modern computing. Current technology uses electric currents which draws a relatively large... -
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... -
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... -
Resonant Spin Excitation in Single Crystal of Ba0.8K0.2Fe2As2
We recently observed a resonant spin excitation in Ba0.6K0.4Fe2As2, one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates that the... -
Neutron scattering study on the phonon spectra of two-dimensional metal chalc...
Two dimensional (2D) metal chalcogenides are constituted by covalently/ionically bonded atomic layers that are held together via interlayer van der Waals (vdW) forces, and... -

The origin of ultra-low thermal conductivity in the thermal barrier material ...
Thermal barrier materials are used in modern turbines to enable them to run above the melting temperature of the turbine blades. However, to go to higher temperatures (and... -
Probing Dirac magnons in a honeycomb ferromagnet
Studying bosonic analogues of fermions in topological electron systems is one of the hottest areas. They are featured by linear band crossing points at finite energy in the... -
Transverse field evolution of magnetic excitation spectrum in Nb1-yFe2+y
Our previous neutron scattering on C14 Laves phase compounds Nb1-yFe2+y revealed that a spin-density-wave (SDW) is masking an underlying ferromagnetic (FM) quantum critical...
