ORIGINAL RESEARCH PAPER

planetary ball mill (Fritsch Pulverisette 6) carried out at 300 rpm for 72 h. In this milling technique, the ferrite powder and zirconia grinding balls (5 and 3 mm in diameter) are used with an approximate ratio by weight of 1:3. Acetone is used as a wet medium to enhance the efficiencyof ball milling and to inhibit the agglomeration of ferrite
