"Topological defects in nanomagnets"

Oleg Tchernyshyov , Johns Hopkins
[Host: Paul Fendley]
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, skyrmions, merons, and magnetic monopoles. I will describe recent experiments with these entities and our attempts to describe their static and dynamic properties.
