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... -
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... -
Phonon Anomalies in YMnO3 at High Temperature
The reported structural phase transition in YMnO3 from P63cm to P63/mmc space group occurs at 1258 ±14 K. For low temperature phase (space group P63cm) the phonon modes are... -
Study of Phonon Anomalies in La and Mn Co-Doped SrTiO3
Thermoelectric device is one of the key devices for the sustainable energy technology. Although semiconductor-based devices are widely used, they sometimes contain toxic,...
