Abstract
Provided is a magnetic element capable of generating one skyrmion and erasing the one skyrmion. The magnetic element includes a magnet shaped like a substantially rectangular flat plate, an upstream electrode connected to the magnet in a width Wm direction of the magnet and made of a non-magnetic metal, a downstream electrode connected to the magnet in the width Wm direction to oppose the upstream electrode and made of a non-magnetic metal, and a skyrmion sensor configured to detect the skyrmion. Here, a width Wm of the substantially rectangular magnet is such that 3·λ>Wm≥λ, where λ denotes a diameter of the skyrmion, a length Hm of the substantially rectangular magnet is such that 2·λ>Hm≥λ, and the magnet has a notch structure at the edge between the upstream electrode and the downstream electrode.
