PURPOSE:To make the growth of ferrite single crystal easy and to reduce the magnetostriction of the single crystal, by using a specific composition of the Li-Fe-Mn- Zn type. CONSTITUTION:The ferrite single cyrstal of this invention has a composition shown by the formula I (x=0.1-0.4, y=0.3-0.55). Since a given amount of Mn<2+> is replaced by a part of Li<+>-Fe<3+>, the single crystal is grown easily with reduced equilibrium oxygen pressure without damaging magnetic properties. The magnetic head materials using this ferrite single crystal slightly cause procesing deterioration resulting from magnetostriction or sliding noise brought about by the slipping between a magnetic tape and a head. |
