| 英文摘要 | In order to obtain mono-dispersed fe nps with high saturation magnetization, quantitative analysis method to investigate the growth dynamics of the fe nps synthesized by a conventional thermal decomposition method has been developed. as a result, fast nucleation process promotes formation of similar to 4 nm of initial nucleus with a non-equilibrium phase, resulting in low saturation magnetization. and slow particle growth with atomic-scaled surface precipitation mode (< 100 atoms/(min.nm(2)))can form the growth layer on the surface of initial nucleus with high saturation magnetization (similar to 190 emu/g(fe)) as an equilibrium a phase of fe. therefore, higher stabilization of small initial nucleus generated just after the injection of fe(co)(5) should be one of the key issues to achieve much higher m(s) of fe nps. |
