Query: Growth and micromagnetism of self-assembled epitaxial fcc(111) cobalt
  dots   We developed the self-assembly of epitaxial submicrometer-sized
face-centered-cubic (fcc) Co(111) dots using pulsed laser deposition. The dots
display atomically-fl at facets, from which the ratios of surface and interface
energies for fcc Co are deduced. Zero- field magnetic structures are
investigated with magnetic force and lorentz microscopies, revealing
vortex-based flux-closure patterns. A good agreement is found with
micromagnetic simulations.
