Two-Dimensional Twisted Ferromagnetic Domain Wall as a Spin-Wave Diffraction Grating
Ehsan Faridi, Se Kwon Kim, Giovanni Vignale
We present a theoretical study of spin-wave scattering by a twisted domain wall (DW) in a two-dimensional ferromagnet with easy-axis anisotropy. While the twisted DW generates an e…

Thermal magnetoresistance from magnon scattering from a domain wall in an antiferromagnetic insulator
Ehsan Faridi, Se Kwon Kim, Giovanni Vignale
We theoretically investigate magnon heat transport in an antiferromagnetic (AFM) insulator containing a domain wall (DW) in the presence of a magnetic field applied along the easy…

Control of spin-wave polarity and velocity using a ferrimagnetic domain wall
Ehsan Faridi, Giovanni Vignale, Se Kwon Kim
We present a theoretical study of the scattering of spin waves by a domain wall (DW) in a ferrimagnetic (FiM) spin chain in which two sublattices carry spins of unequal magnitudes.…
