PROBLEM TO BE SOLVED: To provide a magnetic material from which a very high Q-value can be obtained by controlling the imaginary part of the complex permeability of the material in a high-frequency region, by causing a second phase excluding the spinel phase to appear and, at the same time, adjusting the quantity of the second phase by making the appearance of the phase definite, and to provide coil parts using the material. SOLUTION: The magnetic material is prepared causing a (Cu0.2Ni0.8) oxide phase in a sintered ferrite compact to be scattered and contained with at least the oxides of Fe, Ni, Cu, and Co as main components. |
