| 摘 要： | In 1984, Tanaka et al. synthesized sub-micron scale Fe/N particles with good magnetic char-acteristics (ss≈1×105 A·Wb-1·Kg-1，HC≈3.2×104 A·m-1)[1] by a one-step method of CVD. Since then a few groups have synthesized micron scale, sub-micron scale and nanometer scale nitride-iron particles by different synthesis routes[1—7]. In 1993, Nakatani et al. reported a new method for synthesizing -Fe3N magnetism grain with particle size less than 10 nm[2]. In 1999, Lee et al. reported the…
