Abstract
Currently, one of the biggest challenges in the material science is the miniaturization of transistors and logic devices beyond the CMOS technology. One of the viable alternatives is to employ spintronics, particularly to use the topologically protected spin textures called skyrmions as carriers of bits of information. However, design of devices requires one's ability to precisely control the skyrmion motion and interactions. Therefore, in this PhD the controlled dynamics of skyrmions in a two-dimensional chiral magnet is explored, under influence of driving current and in presence of nanoengineered periodic arrays of pinning centers. The main goal is to map out different dynamic regimes and collective effects encountered during skyrmion motion, as a precursor for their custom-tailored use in information transfer and/or storage.
