The lattice constant (a<SUB>0</SUB>), crystallite size (d) and the crystallite orientation of a-Fe acicular particles in commerciallyavailable audio metal tapes were studied using x-ray diffraction. The value of a<SUB>0</SUB> is determined to be 0.28669 ± 0.00005 nm, which is slightly larger than that of pure Fe. The reason of the small discrepancy of a<SUB>0</SUB> was estimated to be due to 0.1 at%-Al addition into Fe. The acicular particle consists of many crystallite: the crystallite sizes along long axis of acicular particle (22 nm) is larger than the short axis (14 nm). The tendency that the [100] axis of Fe crystallite aligns with the long axis of the acicular particle is observed.
