<P>PROBLEM TO BE SOLVED: To provide a magnetic material for a high-frequency reactor having a high magnetic flux density and a low iron loss at high-frequency. <P>SOLUTION: A soft magnetic material has a resistivity of 70 μΩ.cm or more and a plate thickness of 0.15 mm or less, and its magnetic flux density B<SB>8</SB>is 1.5 T or more. Moreover, the rate of area of fine grains having a crystal grain diameter of 50 μm or less is 25% or more, and the rate of area of coarse grains having a crystal grain diameter of 1.0 mm or more is 25% or more with respect to its crystal texture. <P>COPYRIGHT: (C)2003,JPO |
