چکیده انگلیسی
Fine particles of Fe and Co encapsulated by carbon (C) nanolayers were synthesized through reduction of the metal oxides by C. They were â¼400 nm in diameter, and the shell of the C layers was â¼5 nm in thickness. The Fe particles were composed of mixture of body-centered cubic (BCC), α, and face-centered cubic (FCC), γ-phase, and the Co particles were composed of a FCC, α-phase. Maximum saturation magnetization of the Fe was 101 Am2/kg and that of the Co was 136 Am2/kg. Those C-encapsulated particles showed excellent soft magnetic properties and oxidation resistance in air.
