Title:

FERRITE MATERIAL, METHOD OF PRODUCING FERRITE MATERIAL AND FERRITE MEMBER

Document Type and Number:

Japanese Patent JP2003286071

Kind Code:

A

Abstract:

To provide a cramp with which strain occurring in a magnetic disk can be reduced.

By weight, 0.03 to 0.5% SiO2 more inexpensive than ZrO2 is incorporated into a composition consisting of, by mol, 40 to 49.8% Fe2O3, 10 to 33% ZnO, 2 to 10% CuO and ≤1% Mn2O3, and the balance substantially NiO, so that three-point bending strength of at least 18 kgf/mm2 or higher is obtained.
