Abstract: For uniaxial crystals bulk samples with known structural and magnetic characteristics, it is possible to predict the magnetic domain structure configuration and its elements geometrical parameters. However, this estimation only provides information about the final structure on the basal plane, while the formation features are not considered. In this study, we present a complexity analysis of the domain structure of high- and low-anisotropic compounds, based on its stray field investigation, as well as within the framework of fractal geometry methods. The conducted analysis allowed us to estimate the domain structure complication level through the formation process from bulk domains to the basal plane surface structure. Additionally, based on the scanning probe microscope tips signal spatial distribution, the stray field fractal analysis was carried out. As a result of the obtained data comparison for high- and low-anisotropic compounds, it was shown that the objects with qualitatively different domain structure configurations, but similar formation patterns, have close structure complexity parameter values. At the same time, objects with a simplified structure and a reduced additional domain number have lower values for the structure complexity parameter.
