Nanoscale mechanics of antiferromagnetic domain walls
Natascha Hedrich, Kai Wagner, Oleksandr V. Pylypovskyi +5
Antiferromagnets offer remarkable promise for future spintronics devices, where antiferromagnetic order is exploited to encode information. The control and understanding of antifer…
Curvilinear one-dimensional antiferromagnets
Oleksandr V. Pylypovskyi, Denys Y. Kononenko, Kostiantyn V. Yershov +6
Antiferromagnets host exotic quasiparticles, support high frequency excitations and are key enablers of the prospective spintronic and spin-orbitronic technologies. Here, we propos…
Curvature induced magnonic crystal in nanowires
Anastasiia Korniienko, Volodymyr P. Kravchuk, Oleksandr V. Pylypovskyi +3
A new type of magnonic crystals, curvature induced ones, is realized in ferromagnetic nanowires with periodically deformed shape. A magnon band structure of such crystal is fully d…
Micromagnetic Theory of Curvilinear Ferromagnetic Shells
Denis D. Sheka, Oleksandr V. Pylypovskyi, Pedro Landeros +3
Here, we present a micromagnetic theory of curvilinear ferromagnets, which allows discovering novel fundamental physical effects which were amiss. In spite of the firm confidence f…
Engineered Chiral Skyrmion and Skyrmionium States by the Gradient of Curvature
Oleksandr V. Pylypovskyi, Denys Makarov, Volodymyr P. Kravchuk +3
Curvilinear nanomagnets can support magnetic skyrmions stabilized at a local curvature without any intrinsic chiral interactions. Here, we propose a new mechanism to stabilize chir…
Geometry-induced motion of magnetic domain walls in curved nanostripes
Kostiantyn V. Yershov, Volodymyr P. Kravchuk, Denis D. Sheka +3
Dynamics of topological magnetic textures are typically induced externally by, e.g.~magnetic fields or spin/charge currents. Here, we demonstrate the effect of the internal-to-the-…
