Tès frekans segondè nan konpoze mou mayetik

Gen kèk moun ki sèvi ak cobalt/diyoksid silikon (Co/SiO₂) nanocomposite soft magnetic materials to make large-scale magnetic cores different from thin films. The average size of cobalt particles is 30μm, and the filling degree is 40 percent to 90 percent . After stirring, annealing to form Co/SiO₂nanocomposite poud, ki se Lè sa a, bourade nan yon nwayo bag mayetik. Pèmeyabilite a ka rive jwenn 16 pi ba pase 300MHz. Pèmeyabilite nikèl-zenk ferit se 12 epi li diminye rapidman apre 100MHz. Li pwouve ke konpoze mayetik mou ka ranplase tou yon pati nan mache ferit la nan frekans segondè ak ultra-segondè.
