COMPOSITION, RF DEVICE, MODIFIED NICKEL ZINC FERRITE COMPOSITION AND METHOD FOR FINE TUNING NICKEL-ZINC FERRITE MATERIAL
PROBLEM TO BE SOLVED: To provide a method for fine tuning magnetic properties of nickel zinc ferrite, such as magnetic permeability and magnetic loss by using cobalt (Co) to improve material performance in electronic equipment applications.SOLUTION: There is provided a composition represented by formula NiZnCoMnFeO, where w is larger than 0 and smaller than 0.6, x is larger than 0 and smaller than 0.2, y is larger than 0 and smaller than 0.2, z is larger than 0 and smaller than 0.2, and (a) is larger 0 and smaller than 0.2. A method of fine tuning nickel-zinc ferrite material includes a step 120 for replacing nickel with sufficient Cosuch that a relaxation peak associated with Cosubstitution and a relaxation peak associated with the nickel (Ni) to zinc (Ni/Zn) ratio 110 are nearly coincident with each other. There is provided a composition capable of substantially maximizing material magnetic permeability and substantially minimizing magnetic loss when relaxation peaks partially overlap each other.SELECTED DRAWING: Figure 4
【課題】電子機器用途での材料性能を向上させるために、コバルト（Ｃｏ）を用いて、ニッケル亜鉛フェライトの磁気特性、例えば透磁率及び磁気損失等を微調整する方法の提供。【解決手段】式Ｎｉ１−ｗ−ｘ−ｙ−ｚＺｎｗＣｏｘＭｎｙＦｅ２−ａＯ４−１．５ａにより表される組成物であって、０＜ｗ＜０．６、０＜ｘ＜０．２、０＜ｙ＜０．２、０＜ｚ＜０．２、０＜ａ＜０．２である組成物。Ｃｏ＋２置換に関連付けられた緩和ピークとニッケル（Ｎｉ）対亜鉛（Ｎｉ／Ｚｎ）比１１０に関連付けられた緩和ピークとがほぼ一致するように、ニッケルを十分なＣｏ＋２と置換するステップ１２０を含む。緩和ピーク同士が部分的に重なり合っている場合、材料透磁率を実質的に最大限にすることができ、磁気損失を実質的に最小限にすることができる組成物。【選択図】図４
