We present a phenomenological theory of altermagnets, that captures their unique magnetization dynamics and allows modelling magnetic textures in this new magnetic phase. Focusing on the prototypical d-wave altermagnets, e.g. RuO$_2$, we can explain

Anisotropic effects in antiferromagnetic curvilinear spin chains

Autor: Pylypovskyi, O., Borysenko, Y., Kononenko, D. Y., Yershov, K. V., Roessler, U. K., Tomilo, A., Brink, J., Faßbender, J., Sheka, D. D., Makarov, D.

Curvilinear spin chains are simplest antiferromagnetic systems revealing direct influence of their shape onto magnetic states via geometry-tracking anisotropies stemming from the dipolar interaction [1] or local surrounding [2]. Here, we show that in

Geometry-induced motion of magnetic domain walls in curved nanostripes

Autor: Yershov, K. V., Kravchuk, V. P., Sheka, D. D., Pylypovskyi, O. V., Makarov, D., Gaididei, Y.

Publikováno v: Physical Review B 98(2018), 060409

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-system geometry-induced motion of a domain wall in a curved nanostrip

Rashba Torque Driven Domain Wall Motion in Magnetic Helices

Autor: Pylypovskyi, O. V., Sheka, D. D., Kravchuk, V. P., Yershov, K. V., Makarov, D., Gaididei, Y.

Publikováno v: Scientific Reports 6(2016), 23316

Manipulation of the domain wall propagation in magnetic wires is a key practical task for a number of devices including racetrack memory and magnetic logic. Recently, curvilinear effects emerged as an efficient mean to impact substantially the static
