The effect of capping with Cu, Au and Pt of an array of Co nanoparticles is revised.The magnetic surface anisotropy KS was found to be the dominant contribution to theeffective anisotropy Keff of the particles. Recent X-ray Magnetic Circular Dichroism(XMCD) measurements show that there is hybridization between the 3d Co electronsand the d and 4p electrons of the capping metal. By comparison to the mechanismswhich give rise to the surface anisotropy in thin films, it is argued that this hybridizationgoverns the modification of KS, and hence, of Keff
