PROBLEM TO BE SOLVED: To provide a magnetic material capable of low temperature burning and excellent in core loss properties in a wide frequency range including high frequency region.SOLUTION: There is provided a magnetic material by adding xw% of ZrOand ywt% of NbOas additive agents to a main component containing FeOof amol%, ZnO of bmol% and CuO of cmol% with a+b+c+d=100, 43≤a≤48, 20≤b≤30, 5≤c≤15 as well as 0.5≤x≤0.7 and 0<y≤0.3. The magnetic material to which CaCOof more than 0 wt.% and 0.05 wt.% or less as the additive agent to the main component is preferable.SELECTED DRAWING: None 【課題】低温焼成が可能で、高周波領域を含む広い周波数範囲でのコアロス特性に優れた磁性材料を提供する。【解決手段】Ｆｅ２Ｏ３がａｍｏｌ％、ＺｎＯがｂｍｏｌ％、ＣｕＯがｃｍｏｌ％、残部としてＮｉＯがｄｍｏｌ％含まれている主成分に対して添加剤としてｘｗｔ％のＺｒＯ２とｙｗｔ％のＮｂ２Ｏ５とが添加され、ａ＋ｂ＋ｃ＋ｄ＝１００、４３≦ａ≦４８、２０≦ｂ≦３０、５≦ｃ≦１５であるとともに、０．５≦ｘ≦０．７、０＜ｙ≦０．３であることを特徴とする磁性材料としている。前記主成分に対して添加剤としてＣａＣＯ３が０ｗｔ％よりも多く０．０５ｗｔ％以下で添加されている磁性材料とすればより好ましい。【選択図】なし
