Abstract: The present disclosure relates to an apparatus for generating, erasing, and moving a skyrmion in a magnetic thin film. The apparatus for generating, erasing, and moving the skyrmion may include: a first electrode to which a first voltage for generating and erasing the skyrmion is applied; a second electrode to which a second voltage for moving the generated skyrmion is applied; a free layer having one end connected to a ground and the other end connected to the second electrode; a pinned layer which is connected to the first electrode; and a barrier layer which is provided between the free layer and the pinned layer and includes a conducting path connecting the free layer and the pinned layer.

Abstract: The present disclosure relates to a device and method for forming skyrmion in a magnetic thin film. A skyrmion forming method comprises aligning the surface of the magnetic thin film and a horizontal magnetic field to be applied to the magnetic thin film and applying the horizontal magnetic field and a vertical magnetic field to the magnetic thin film. Accordingly, it is possible to form the bubble skyrmion easily even in the case of a wide width of a stripe formed on the magnetic thin film.
