摘要：

NiO nanoparticles are synthesized by vacuum arc sputtering. The effect of the synthesis parameters on the structural and magnetic properties of samples is studied. X-ray diffraction analysis confirms a polycrystalline structure of the nanoparticles prepared under all deposition conditions; however, the preferred orientation of crystallites depends on the deposition conditions. The magnetic behavior correlates with the crystallite size of NiO nanoparticles. Condensates with a particle size of 4-6 nm demonstrate superparamagnetic behavior, which changes into antiferromagnetic as the particle size increases.
