Title:
INDUCTOR ELEMENT AND APPARATUS INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2020/027268
Kind Code:
A1
Abstract:
In order to obtain an inductor element advantageous for miniaturization, an inductor element 10 according to an embodiment of the present disclosure is provided with a metal medium 2 in which ordered spins are spatially oriented so as to have a non-collinear spin structure when traced in a certain direction. In the inductor element, an electric current I is flowed through the metal medium so as to have a projective component of the direction. Preferable examples of the non-collinear spin structure for the metal medium include a spiral structure and a cycloidal structure.
