Using a new micro-SQUID setup, we investigate magnetic anisotropy in a single 1000-atom cobalt cluster. This system opens new fields in the characterization and understanding of the origin of magnetic anisotropy in such nanoparticles. For this purpose, we report three-dimensional switching field measurements performed on a 3 nm cobalt cluster embedded in a niobium matrix. We are able to separate the different magnetic anisotropy contributions and evidence the dominating role of the cluster… Expand
Magnetic anisotropy of nanoscale cobalt particles
We report calculations of the magnetic anisotropy energy (MAE) of cobalt nanoparticles in the size range 300–1000 atoms. The MAE is expressed in terms of shell-resolved contributions from differentExpand
Magnetic anisotropy in single clusters
The magnetic measurements on single cobalt and iron nanoclusters containing almost 1000 atoms are presented. Particles are directly buried within the superconducting film of a micro-SQUIDExpand
Temperature dependence of switching fields of single 3 nm cobalt nanoparticles
We study the temperature dependence of the magnetization switching fields of single nanoparticles with an improved micro-superconducting quantum interference device (SQUID) technique, that allows usExpand
Three dimensional arrays of cobalt nanocrystals: Fabrication and magnetic properties
Cobalt nanocrystal three dimensional (3D) arrays were fabricated by deposition of a ferrofluid on a highly oriented pyrolitic graphite substrate and by applying a magnetic field parallel to theExpand
Probing planar arrays of magnetic nano-particles by the extraordinary Hall effect
The extraordinary Hall effect has been used to determine the blocking temperature, magnetocrystalline anisotropy and magnetic moment of far-separated Co nano-particles arranged in single-layerExpand
Magnetic anisotropy of isolated cobalt nanoplatelets
Motivated in part by experiments performed by M.H. Pan et al. (nanoletters, v.5, p 83, 2005), we have undertaken a theoretical study of the the magnetic properties of two-monolayer thick CoExpand
Surface-induced cubic anisotropy in nanomagnets
We investigate the effect of surface anisotropy in a spherical many-spin magnetic nanoparticle. By computing minor loops, two-dimensional (2D) and 3D energyscape, and by investigating the behavior ofExpand
Size effects of the magnetic anisotropy of fcc cobalt nanoparticles embedded in copper
Abstract Cobalt nanoparticles embedded in copper matrices show strong size effects in the magnetic anisotropy with a non-monotonous dependence on the particle diameter. In this article we discussExpand
Size effects in the magnetic anisotropy of embedded cobalt nanoparticles: from shape to surface
Strong size-dependent variations of the magnetic anisotropy of embedded cobalt clusters are evidenced quantitatively by combining magnetic experiments and advanced data treatment. The obtained valuesExpand
Possibility of superradiance by magnetic nanoclusters
The possibility of realizing spin superradiance by an assembly of magnetic nanoclusters is analyzed. The known obstacles for realizing such a coherent radiation by magnetic nanoclusters are theirExpand
