Abstract

Ba-M ferrite fine particles were prepared by mechanical compounding method using the planetary ball-mill and subsequent heat treatment. The conditions determined as optimum for the preparation of Ba-M ferrite fine particles having a somewhat similar diameter to the single domain are as follows : chemical composition-BaO⋅5Fe₂O₃ ; planetary ball-mill condition : 300rpm×lh ; heating condition : 1100°C×1h in air ; magnetic and physical properties are σ_s=82.5×10^-6wb⋅m/kg, H_cJ=326.3kA/m, T_c=450.6°C, lattice constant a=5.874×10^-10m, c=23.22×10^-10m and average particle size 0.41μm.
