| 中文摘要 | Fe-Co magnetic nanopowders were prepared by chemical vapor condensation (CVC) process, and some of their characteristics such as size, phase, oxidation behavior, and magnetic properties were investigated. Thermal behaviors of Fe-Co nanopowders were also studied by means of annealing in the air. Iron pentacarbonyl (Fe(CO)(5)) and dicobalt octacarbonyl (Co-2(CO)(8)) were used as precursors. XRD patterns showed that Fe-Co nanopowders were obtained in pure Ar, but that the Fe and Co oxide nanopowders were produced in the Ar + O-2 mixtures. Fe-Co nanopowders obtained in pure Ar consist of a core and a shell with a thickness of 2-4 nm. The saturation magnetization and coercivity decreased with increasing oxygen content in the carrier gases. The CVC nanopowders obtained in different carrier gases showed different Mossbauer spectrums. |
