Abstract
We report on the size, structure and magnetic properties of Ni nanoparticles fabricated with a free-jet sputtering nanoparticle source. It is found how the pressure of the inert gas and the diameter of the source nozzle can control the particle size and coercivity in a wide range. Measurements of the specific magnetic moment of Ni nanoparticles are reported. A particular growing regime is found at high pressures over 1.8Â mbar observing a further aggregation process that leads to nanoparticle agglomerates with diameters larger than 100Â nm with a low dispersion in size.
