Nichtmagnetischer Mn-Zn-Ferrit-Einkristall für schwebende Magnetköpfe |
摘要 |
A non-magnetic single crystal of Mn-Zn ferrite being obtained by a solid phase reaction process including the steps of contacting a seed single crystal ferrite with a polycrystal crystal ferrite and producing said single crystal by growing the single crystal in a direction from the seed single crystal toward the polycrystal under heating. The single crystal of Mn-Zn ferrite has a composition defined by points A, B, C, D and E in a three-phase diagram of Fe2O3-MnO-ZnO, in which: A: Fe2O3 40 mol%, MnO 10 mol %, ZnO 50 mol%; B: Fe2O3 40 mol%, MnO 35 mol %, ZnO 25 mol%; C: Fe2O3 70 mol%, MnO 5 mol %, ZnO 25 mol%; D: Fe2O3 70 mol%, MnO 2 mol %, ZnO 28 mol%; and E: Fe2O3 48 mol%, MnO 2 mol %, ZnO 50 mol%. |
