Sažetak
We present the investigation of self-organization and physical properties of Ni nanoparticles within the dielectric matrix prepared by the simple method of sequential magnetron sputtering deposition of two alternating Al_2O_3 and Ni+Al_2O_3 layers. The self-assembly mechanism of nanoparticle growth results in the uniform nanoparticle sizes and their regular arrangement in the 2D/3D lattice via the combination of diffusion and surface morphology effects. We investigate the dependence of the structural and magnetic properties of the formed lattices on various deposition conditions. The structure of the films was analyzed using Grazing Incidence Small and Wide Angle X-ray Scattering, and Time- of-Flight Elastic Recoil Detection Analysis measurements, while the magnetic properties were studied by SQUID magnetometry. The obtained results are important for the tailoring of physical properties of Ni NP lattices in amorphous matrices and the applications of such materials. The prepared materials are potentially interesting for spintronic applications.
