MAGNETIC MATERIAL, AND LAMINATED CHIP COMPONENT
To provide a magnetic material that can be fired at low temperature and can be used even in a high frequency region, and has high magnetic properties.SOLUTION: A magnetic material has a main component composed of ferrite, to which accessory components are added. The main component has a mol% of FeO, b mol% of ZnO, c mol% of CuO, and d mol% of NiO. For the accessory components, e wt.% of CoO, f wt.% of ZrO, and g wt.% of BiOare added relative to the main component, and x wt.% of Ba or Sr is added in terms of BaCOor SrCO. Following relations are established: a+b+c+d=100, 40≤a≤45, 0
【課題】低温焼成が可能であるとともに、高い周波数領域でも使用可能で、かつ高い磁気特性を備えた磁性材料を提供する。【解決手段】フェライトからなる主成分に副成分が添加されてなる磁性材料であって、主成分は、ａｍｏｌ％のＦｅ２Ｏ３と、ｂｍｏｌ％のＺｎＯと、ｃｍｏｌ％のＣｕＯと、ｄｍｏｌ％のＮｉＯとを含み、副成分は、主成分に対して、ｅｗｔ％のＣｏＯと、ｆｗｔ％のＺｒＯ２と、ｇｗｔ％のＢｉ２Ｏ３とが添加されているとともに、ＢａあるいはＳｒがＢａＣＯ３あるいはＳｒＣＯ３換算でｘｗｔ％添加され、ａ＋ｂ＋ｃ＋ｄ＝１００、４０≦ａ≦４５、０＜ｂ≦１０、０＜ｃ≦１５、０＜ｅ≦１．０、０＜ｆ≦０．５、０＜ｇ≦０．５、０＜ｘ≦０．３である。【選択図】なし
