We develop the self-assembly of epitaxial submicrometer-sized face-centered-cubic (fcc) Co(111) dots using pulsed laser deposition. The dots display atomically flat 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.

Magnetic domains and magnetostatic interactions of self-assembled Co dots
Submicron quasihexagonal Co dots and dot chains have been grown epitaxially on Ru(0001) substrate with molecular beam epitaxy and investigated with magnetic force microscopy. All the dots exhibit
Self-organization and magnetic domain microstructure of Fe nanowire arrays
Starting from essentially flat nanometer-thick Fe films, epitaxially grown at room temperature on W(110) surfaces, we used carefully tuned annealing schedules to produce periodic arrays of nanoscale

Nanowires formation and the origin of ferromagnetism in a diluted magnetic oxide
The ferromagnetic response from Co-doped CeO(2) epilayers is shown to be linked to the formation of Co metallic nanowires (diameters in the 3-7 nm range) within the oxide matrix. These results (i)
Three-dimensional magnetic-flux-closure patterns in mesoscopic Fe islands
We have investigated three-dimensional magnetization structures in numerous mesoscopic Fe/Mo(110) islands by means of x-ray magnetic circular dichroism combined with photoemission electron microscopy
Preparation and characterization of Co single-crystal thin films with hcp, fcc and bcc structures
Co crystals with three different structures are realized in the form of single-crystalthin films hetero-epitaxially grown on single-crystal substrates by ultrahigh vacuum rf magnetron sputtering.
Magnetic bistability of Co nanodots.
Both single-domain and vortex states can be stabilized in a broad region near the phase boundary and the calculated width of the bistability region and temperature dependent heights of the energy barriers between both states agree well with the experimental findings.
