Positional memory of skyrmions in magnetic bilayers
Bruno Barton-Singer, Anusree Navallur, Stavros Komineas
We numerically and analytically study the transient dynamics of magnetic skyrmions in synthetic antiferromagnets under a magnetic field gradient. We consider skyrmions in a bilayer…
Antiferromagnetic domain walls under spin-orbit torque
George Theodorou, Stavros Komineas
Domain walls in antiferromagnets under a spin-polarized current present dynamical behavior that is not observed in ferromagnets, and it is tunable by the current polarization. Prec…
Traveling antiferromagnetic domain walls in a magnetic field
George Theodorou, Stavros Komineas
We consider an antiferromagnet in one space dimension with easy-axis anisotropy in a perpendicular magnetic field. We study propagating domain wall solutions that can have a veloci…
Interaction and collision of skyrmions in chiral antiferromagnets
George Theodorou, Bruno Barton-Singer, Stavros Komineas
Skyrmions in an antiferromagnet can travel as solitary waves in stark contrast to the situation in ferromagnets. Traveling skyrmion solutions have been found numerically in chiral…
Meron configurations in easy-plane chiral magnets
David Bachmann, Michail Lianeris, Stavros Komineas
We demonstrate the existence and study in detail the features of chiral bimerons which are static solutions in an easy-plane magnet with the Dzyaloshinskii-Moriya (DM) interaction.…
Non-Hermitian dynamics of a two-spin system with PT symmetry
Stavros Komineas
A system of interacting spins that are under the influence of spin-polarized currents can be described using a complex functional, or a non-Hermitian (NH) Hamiltonian. We study the…
