Sodium hydroxide (70 ml) was taken from one molar solution in approximately 1760 ml of distilled water to have the concentration of 0.37 mol/l and heated to boiling.

Mn¨CZn ferrite of composition Mn0.4Zn0.6Fe2O4 was
prepared by the co-precipitation method. The materials
used were manganese chloride (98% Merck, India), zinc
chloride (96% Merck, India), iron (III) chloride (98%
Merck, India) and sodium hydroxide (96% Merck, India).
One molar solution of these materials was made with
distilled water. Sodium hydroxide (70 ml) was taken from
one molar solution in approximately 1760 ml of distilled
water to have the concentration of 0.37 mol/l and heated to
boiling. Manganese chloride, zinc chloride and iron (III)
chloride were taken from their molar solution in accurate
stoichiometric proportions. These solutions were poured as
quickly as possible into the boiling solution of NaOH
under vigorous stirring produced by the glass mechanical
stirrer (500 rpm). Mixing is very important;
