High zaus xeem ntawm Soft Magnetic Composites

Qee tus neeg siv cobalt / silicon dioxide (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 hmoov, uas yog ces nias rau hauv lub nplhaib sib nqus core. Lub permeability tuaj yeem ncav cuag 16 hauv qab 300MHz. Qhov permeability ntawm npib tsib xee-zinc ferrite yog 12 thiab txo qis tom qab 100MHz. Nws tau raug pov thawj tias cov khoom sib nqus mos kuj tuaj yeem hloov tau ib feem ntawm kev lag luam ferrite ntawm siab thiab ultra-siab zaus.
