摘要: In this work, the magnetic properties and electrical conductivity of carbon–nickel composite films deposited at different deposition times 50–600 s were investigated. The grown by radio frequency magnetron co-sputtering on glass substrates room temperature. nickel concentration in are effected changing rate measured energy dispersive X-ray studies. Values coercive field under both increasing decreasing applied field. It is shown that strongly dependent nanoparticle size 180 has maximum value 68.04 (Oe). difference fields increased for from 50 to then decreased 600 s. ID/IG ratio Raman spectra would indicate presence higher sp2 bonded carbon For entire temperature range (15–500 K), up increases it decreases. These observations a good agreement with emission scanning electronic microscopy (FESEM) images.
