<P>PROBLEM TO BE SOLVED: To provide an Fe-Ni-Mo flaky metal soft magnetic powder, and to provide an Fe-Ni-Mo oxide film-coated flaky metal soft magnetic powder obtained by forming an oxide film on the surface of the powder. <P>SOLUTION: A flaky metal soft magnetic powder having a component composition of, in percent by mass: Ni=60 to 90%; Mo=0.05 to 1.95%; and the balance of Fe and unavoidable impurities, an average particle size of 30 to 150 μm, and a flat surface with an aspect ratio of 5 to 500. Under the condition that the plane including the direction in which X-rays enters and the direction of diffraction is perpendicular to the flat surface of the flaky metal soft magnetic powder, and the angle between the X-ray entrance direction and the flat surface is equal to the angle between the diffraction direction and the flat surface, the X-ray diffraction pattern is measured. The peak intensity ratio I<SB>200</SB>/I<SB>111</SB>is in the range from 0.43 to 10 where I<SB>200</SB>is the peak height of the face index (200) of the X-ray diffraction pattern and I<SB>111</SB>is the peak height of the face index (111) thereof. Further, the oxide film coated flaky metal soft magnetic powder is obtained by forming an oxide film on the surface of the flaky metal soft magnetic powder. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
