Abstract

Whether in the compass in the early ages of mankind or in the hard disk drives that provide the vast quantities of memory that nowadays information technology demands: magnetism is a ubiquitous phenomenon with numerous applications in our everyday life. The comparatively young skyrmion, in turn, adds with its topologically non-trivial structure a new flavor to this extensively studied field. This cumulative dissertation explores the diverse phenomena that occur in magnets, where non-collinear magnetization-textures are stabilized as a consequence of broken mirror or inversion symmetries of the material. These textures include long-ranged spirals, lattices of skyrmions, and polarized structures.
