Monocrystalline MnZn-ferroferrite material having a high content of Zn, and a magnetic head manufactured from said material. |
| 摘要 |
A monocrystalline MnZn-ferroferrite material for use is a magentic head is described. The material corresponds to the formula MnaZnbFec<II>Fe2<III>O4, wherein 0.25 < a < 0.48; 0.50 < b < 0.60; 0.02 < c < 0.15; a + b + c = 1. The magnetostriction constants of this material are particularly small. |
