    • Topological defects in flat nanomagnets: the magnetostatic limit 

      Chern, G.-W.; Youk, H.; Tchernyshyov, O. (American Institute of Physics, 2006-04-15)
      We discuss elementary topological defects in soft magnetic nanoparticles in the thin-film geometry. In the limit dominated by magnetostatic forces the low-energy defects are vortices (winding number n=+1), cross ties (n=-1), ...
