    摘要： Provided is a magnetic element, a skyrmion memory, and the like that have a nearly infinite endurance (durability) for the number of times data is written and nearly eternal data retention (holding) characteristics, and are capable of writing and erasing at ultra-high speed. For example, provided is a magnetic element capable of generating and erasing a skyrmion, including a magnet shaped as a thin layer and including a structure surrounded by a nonmagnetic material; a current path provided surrounding an end region including an end portion of the magnet, on one surface of the magnet; and a skyrmion sensor that detects the generation and erasing of the skyrmion. With Wm being a width of the magnet and hm being a height of the magnet, a size of the magnet, with the skyrmion of a diameter λ being generated, is such that 2λ > Wm > λ/2 and 2λ > hm > λ/2. With W being a width of the end region in a direction parallel to the end portion of the magnet and h being a height of the end region in a direction perpendicular to the end portion of the magnet, the end region is such that λ ≥ W > λ/4 and 2λ > h > λ/2.
