Abstract
A spin-orbit-torque magnetization rotational element includes: a ferromagnetic metal layer, a magnetization direction of the ferromagnetic metal layer being configured to change; a spin-orbit torque wiring which extends in the first direction intersecting a lamination direction of the ferromagnetic metal layer and is joined to the ferromagnetic metal layer; and two via wires, each of which extends in a direction intersecting the spin-orbit torque wiring from a surface of the spin-orbit torque wiring opposite to a side with the ferromagnetic metal layer and is connected to a semiconductor circuit, wherein a via-to-via distance between the two via wires in the first direction is shorter than a width of the ferromagnetic metal layer in the first direction.
