description: In this paper, the magnetic properties of CuO nanoparticles are investigated. The sample was obtained by evaporation of composite copper-containing graphite electrodes in the plasma of an electric arc generator and subsequent calcination of condensate in a muffle furnace at 650Â°C. The material has a residual magnetization of 0.5 emu/G at a temperature of 400 K, actively reacts to a permanent magnet. Graphs of the dependence of magnetization on temperature and external field are obtained. The magnetization of the sample is several orders of magnitude higher than the results of the magnetization of CuO in the previously published literature. Elemental analysis, together with raman spectroscopy, made it possible to establish the presence of a strong magnetic phase CuFe2O4 in the sample. The unique properties of the obtained material allow them to be widely used in various fields, such as catalysis, optoelectronics, as sensors, as antimicrobial agents.
