Embodiment Construction

[0038] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Preferred embodiments of the application are shown in the accompanying drawings. However, the present application can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the application more thorough and comprehensive.

[0039] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention relates to a logic device for driving magnetic skyrmion based on spin waves, which is an AND gate, and comprises a spin wave excitation source used for generating spin waves and comprising two excitation sources at a first input end and a second input end; a magnetic nanometer track which is composed of a magnetic material layer and a strong spin track material layer and comprises five tracks, one end of the first track is connected with one end of the second track and one end of the third track, and the other end of the first track is connected with one end of the fourth track and one end of the fifth track; one ends of the second rail and the third rail are respectively connected with the first rail, and the other ends are respectively a first output end and a first input end; one end of the fourth rail and one end of the fifth rail are connected with the other end of the first rail and serve as a second input end and a second output end respectively. The logic device is realized by driving the magnetic skyrmion through spin waves, and has the characteristics of low temperature, high stability and long service life.

Description

technical field [0001] The invention relates to the technical field of logic devices, in particular to a logic device based on spin wave driving magnetic skyrmions. Background technique [0002] Compared with microelectronic logic devices, magnetic skyrmions have the advantages of small size, high stability, and high speed. At present, the main means of driving magnetic skyrmions is current drive, which will generate a large amount of Joule heat in the device and device, which will affect the stability of magnetic skyrmions and the service life of the device. Contents of the invention [0003] Based on this, it is necessary to provide a logic device that drives magnetic skyrmions based on spin waves. [0004] A logic device for driving magnetic skyrmions based on spin waves, the logic device is an AND gate, comprising: [0005] The spin wave excitation source is used to generate spin waves, including a first excitation source placed at the first input end; a second excit...
