| Abstract: | In this paper, the properties of fractal aggregates formed by single-domain particles is dis-cussed, the expresssion of coercivity of fractal aggregates is derived with dipole field approximation,the relationship between fractal dimension and packing density is obtained, which is quantitatively con-sistent with experimental results, and the semi-empirical formula of coercivity is derived theoretically. |
