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…
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…
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…
