Abstract

We have studied the static magnetic properties of nanocrystalline Co-Ti doped barium ferrite BaFe_10.4Co_0.8Ti_0.8O₁₉. The zero-field-cooled (ZFC) and field-cooled (FC) processes show the typical features of a small particle system. The dependence on temperature of the coercive field is discussed within the scope of an aligned and random assembly of particles. The distribution of blocking temperatures is obtained from the remanent-to-saturation magnetization ratio, leading to the mean volume of the magnetic unit (≈(6±3)·10⁴ A³), in agreement with the mean particle volume determined by TEM (≈1.1·10⁵ A³). Remanence curves are used to derive the anisotropy field distribution and the interparticle magnetic interaction.
