Abstract
Official abstract text for this publication.
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 arranged so as to have a non-collinear spin structure when traced in a certain direction. In the inductor element, an electric current I is applied 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An inductor element comprising: a metal medium, wherein the metal medium has a spatial arrangement of ordered spins throughout the metal medium, the spatial arrangement of ordered spins being configured to have a non-collinear spin structure when traced in a direction, wherein the metal medium has an inductive property when an alternating electric current is applied through the metal medium, the alternating electric current being configured to have a projection component in the direction, and the non-collinear spin structure generating an emergent electric field through deformation of the spatial arrangement of ordered spins caused by the alternating electric current, and the emergent electric field being observed as a voltage drop in the metal medium leading to the inductive property, and wherein the spatial arrangement of ordered spins is other than a skyrmion or a helix structure. 2. The inductor element according to claim 1 , wherein the metal medium is a material with the spatial arrangement of a helical structure whose wave vector direction is aligned with the direction. 3. The inductor element according to claim 1 , wherein the metal medium is a material with the spatial arrangement of a cycloidal structure whose wave vector direction is aligned with the direction. 4. The inductor element according to claim 1 , wherein the metal medium is a material with a ferromagnetic order in which adjacent ordered spins are substantially ferromagnetic. 5. An apparatus comprising an inductor element according to claim 1 .
