る(特開昭59−47352号公報)。One of the important properties of these products is good eddy current loss characteristics (lower eddy current loss). One method for improving the eddy current loss characteristics is to make the ultra-quenched magnetic alloy ribbon thinner to increase its electrical resistance. However, there are technical limits to reducing the thickness of ultra-quenched magnetic alloy ribbons, and therefore, as another method to reduce eddy current loss in the high frequency range, we have developed After adding a solid solution powder, the molten metal is ejected from a nozzle/slit onto the surface of a rotating cooling roll to disperse the non-solid solution powder in the magnetic alloy matrix, thereby making use of a so-called second phase particle-dispersed ultra-quenched alloy. has been proposed (Japanese Unexamined Patent Publication No. 59-47352).

めて有効である。By the way, the eddy current loss PE of the Fe-based ultra-quenched magnetic alloy in the high frequency region is estimated to be 90 inches or more of the total loss. In order to lower this PK, 2L in equation (2) should be made smaller. Reducing 2L means subdividing the magnetic domain of the magnetic alloy and increasing the number of domain walls. In the present invention, compounds such as oxides or nitrides are generated on the surface of the ultra-quenched magnetic alloy ribbon by heat-treating the ultra-quenched magnetic alloy ribbon in a predetermined atmosphere (air or nitrogen gas). An ultra-quenched composite magnetic alloy with low eddy current loss can be obtained. The above-mentioned compounds were heated for a short period of time at low temperatures (200
~300°C) In order to easily generate on the surface of ultra-quenched magnetic alloy ribbon through heat treatment, it is extremely effective to add 5% or less of a metal whose compound formation free energy is lower than that of the main component of the base material. .
