Condensed-matter systems with Dzyaloshinskii-Moriya interaction offer
exciting opportunities to form various spin textures, such as tilted
domain walls, skyrmions and antiskyrmions. I will talk about these
magnetic textures, the conditions when they can be formed, their
internal structure, and dynamics due to spin-orbit torques. I will
start with ferromagnetic systems and discuss how surface curvature and
disorder may affect these textures and their dynamics. Then I will move
on to antiferromagnets where I will discuss the stability and peculiar
dynamics of skyrmions showing no skyrmion Hall effect.
