Laminated magnetic material and method of producing the same. |
摘要 |
<p>A laminated magnetic material suitable for use as a material of a magnetic core has a plurality of layers of an Fe-Si-Al type magnetic metal and a plurality of electrically insulating layers both of which layers are laminated alternatingly, the magnetic metal containing 0.001 to 0.3 wt% of oxygen. The laminated magnetic material can be produced by forming, on a base film, a film made of a magnetic powder of an Fe-Si-Al type metal containing 0.001 to 0.3 wt% of oxygen, separating the film of the magnetic powder from the base film, laminating the separated film of magnetic powder so as to form a laminated structure, and extruding the laminated structure.</p> |
