Selected results of experimental and theoretical studies of ultrathin magnetic layers (mainly cobalt) will be presented. Interfaces between Co and surrounding layers have strong influence on magnetic properties such as magnetic anisotropy, interlayer coupling or Dzyaloshinskii–Moriya interaction (DMI) responsible for statics (dynamics) of magnetization distribution, creation of intensively investigated now magnetic structures such as skyrmions, spin spirals. Reversible and irreversible driving of magnetic properties is possible during samples deposition and post-growth processes: annealing (also by laser pulses) and ion bombardment. While properly changing magnetic sample history one can obtain different metastable magnetic distributions with huge difference in domain sizes. Some examples of comparison between magnetic nanostructures and bulk materials will be shown.
