The interplay of local and long-range forces in ferromagnets leads to
the formation of mesoscopic domains with sharp boundaries (domain
walls). The physics changes drastically when the magnet size becomes
smaller than the width of a domain wall. In submicron magnets the
magnetization forms intricate smooth patterns that involve the more
exotic topological defects: integer and fractional vortices,
merons, and magnetic monopoles. I will describe recent experiments
these entities and our attempts to describe their static and dynamic
