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…
Nonconserved Density Accumulations in Orbital Hall Transport: Insights from Linear Response Theory
Hao Sun, Alexander Kazantsev, Alessandro Principi +1
We present a linear response theory for stationary density accumulations in anomalous transport phenomena, such as the orbital Hall effect, where the transported density is odd und…
Orbital Magnetic Moment Dynamics and Hanle Magnetoresistance in Multilayered 2D Materials
Hao Sun, Giovanni Vignale
The orbital Hall effect (OHE), resulting from non-trivial quantum geometry of 2D materials, has several potential advantages over the spin Hall effect (SHE), the latter being well…
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.…
Collective charge-density excitations of non-circular quantum dots in a magnetic field
C. A. Ullrich, G. Vignale
Recent photoabsorption measurements have revealed a rich fine structure in the collective charge-density excitation spectrum of few-electron quantum dots in the presence of magneti…
