Title: Influence of shape, size and internal structure on magnetic properties of core-edge nanodots with perpendicular anisotropy

The properties of perpendicularly magnetized isolated nanodots different in shape, size, and internal structure are simulated by micromagnetic calculations. Investigated dots are magnetically uniform, or they are composed of a core and an edge characterized by different anisotropy—stronger or weaker than that of the core. Based on calculated hysteresis loops, we discuss in details the magnetization reversal processes, stability of magnetic structures, and spin configurations in the dots.
