摘要	The boron-oxide coated iron nanocapsules have been prepared by arc-discharge in a mixture of diborane and nitrogen, and then the boron-nitride coated iron nanocapsules by a subsequent annealing under a nitrogen atmosphere at 1100 degrees C. After the arc-discharge, the boron-oxide coated iron nanocapsules form, which show an amorphous surface layer of B(2)O(3) (and/or B) and a core of gamma-Fe, alpha-Fe, FeB phases. After being annealed, part of the a-Fe phase transforms to the gamma-Fe phase, and the FeB phase decomposes while the BN phase forms. The BN shell structure formed in the BN encapsulating iron nanocapsules is incomplete. Magnetic properties of the boron-oxide coated and the boron-nitride coated iron nanocapsules were compared and discussed in terms of the particles' sizes, the phase components, and the surface structures.
