Abstract
An Fe-based nanocrystalline alloy ribbon, the ribbon including an uneven structure on a surface of the ribbon, in which the uneven structure includes at least one recessed portion that extends along a longitudinal direction of the ribbon and that has a depth of 3 μm or more, and the ribbon includes a magnetic domain that is formed along a width direction intersecting the longitudinal direction.
Claims14
An Fe-based nanocrystalline alloy ribbon, the ribbon comprising an uneven structure on a surface of the ribbon,
- wherein the uneven structure comprises at least one recessed portion that extends along a longitudinal direction of the ribbon and that has a depth of 3 μm or more, and
- the ribbon comprises a magnetic domain that is formed along a width direction intersecting the longitudinal direction.
An Fe-based nanocrystalline alloy ribbon, the ribbon comprising an uneven structure on a surface of the ribbon,
- wherein the uneven structure has a maximum height roughness Rz of 3 μm or more in a width direction of the ribbon, and
- the ribbon comprises a magnetic domain that is formed along the width direction.
A wound core comprising:
- an Fe-based nanocrystalline alloy ribbon, wherein
- the wound core comprises a region where the ribbon is continuous along a height direction of the wound core,
- the region has a width of 2.5 mm or less, and
- the wound core comprises a magnetic domain that is formed along the height direction of the wound core.
