Embodiment Construction
[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0025] The track memory based on magnetic skyrmions provided by the present invention includes antiferromagnetically coupled dual-track magnetic nanobelts, and the dual-track magnetic nanobelts can be magnetic thin films arranged on a substrate, and in some embodiments, the size is 200nm*1800nm *1nm, the magnetic material is the martensitic phase of the Heusler-type magnetic shape memory alloy.
[0026] The double-track magnetic nanoribbon is divided into information writing part, information storage part and information reading part along its track direction, and the magnetic skyrmion with opposite polarity is used to represent the binary number 0 or 1, and the magnetic skyrmion is in the The information writing part is generated, and then read by the information reading part after passing through the information storing part.
