Abstract
Official abstract text for this publication.
A material containing a soft magnetic substance is subjected to a plastic deformation such as a roll processing to obtain a rod-shaped body. Then, the rod-shaped body or a shaped body obtained by processing the rod-shaped body into a shape other than a flat plate shape is subjected to a heat treatment in the presence of a magnetic field. The rod-shaped body or the shaped body is made magnetic-anisotropic by the heat treatment thereby to obtain a magnetic-anisotropic plastically deformed body.
First claim
Opening claim text (preview).
What is claimed is: 1. A magnetic-anisotropic plastically deformed body comprising a plastically deformed body obtained by plastic deformation of a single material containing a soft magnetic substance into a shape other than a flat plate shape, the plastically deformed body exhibiting a magnetic anisotropy. 2. The magnetic-anisotropic plastically deformed body according to claim 1 , having one magnetization easy axis oriented in an arbitrary direction, thereby…
