Spin wave vortex from the scattering on Bloch point solitons
(Elsevier, 2015)
The interaction of a spin wave with a stationary Bloch point is studied. The topological non-trivial structure of the Bloch point manifests in the propagation of spin waves endowing them with a gauge potential that resembles ...

Magnons in a Ferromagnetic Monolayer
(AMER PHYSICAL SOC, 2009)
We report the first observation of high wave vector magnon excitations in a ferromagnetic monolayer. Using spin-polarized electron energy loss spectroscopy, we observed the magnon dispersion in one atomic layer (ML) of Fe ...
Magnonic Black Holes
(American Physical Society, 2017)
© 2017 American Physical Society.We show that the interaction between the spin-polarized current and the magnetization dynamics can be used to implement black-hole and white-hole horizons for magnons - the quanta of ...
Magnonic Black Holes
(2017)
We show that the interaction between the spin-polarized current and the magnetization dynamics can be used to implement black-hole and white-hole horizons for magnons-the quanta of oscillations in the magnetization direction ...
Topological magnonics in the two-dimensional van der Waals magnet CrI3
(Amer Physical Soc, 2020)
We report on the magnon spectrum of Kitaev-Heisenberg magnets and extract the parameters to model a two-dimensional CrI3. Our minimal spin Hamiltonian includes a contribution stemming from a Heisenberg, isotropic exchange, ...
Magnons and excitation continuum in XXZ triangular antiferromagnetic model: Application to Ba3CoSb2O9
(American Physical Society, 2015-04)
We investigate the excitation spectrum of the triangular-lattice antiferromagnetic XXZ model using series expansion and mean field Schwinger boson approaches. The single-magnon spectrum computed with series expansion ...
