Abstract

A reconfigurable logic gate based on magnetic skyrmions belongs to the technical field of magnetic devices. The present invention ameliorate the problem of data loss and misreading by using magnetic skyrmions of polarity +1 or -1 to represent logic 1 and logic 0. By changing the voltage to control the connection port of the magnetic anisotropic gate power supply to realize the conversion of the AND gate and the OR gate, the invention greatly optimizes the manufacturing process. Driven by the current, the present invention uses twisted magnetic skyrmions to move along the antiferromagnetic boundary, two twisted magnetic skyrmions can fuse into one twisted magnetic skyrmion, and the topological charge is +1 or -1 magnetic Skyrmions can be transformed into twisted magnetic skyrmions, and twisted magnetic skyrmions can also be transformed into magnetic skyrmions with topological charges of +1 or -1, etc., to realize logic operations based on magnetic skyrmions. The logic gate of the invention has the characteristics of small size, low power consumption, high stability, fast operation speed and the like.

Description

technical field [0001] The invention belongs to the technical field of magnetic devices, in particular to a reconfigurable logic gate based on magnetic skyrmions, which can realize logical AND and logical OR. Background technique [0002] Logic gates are the cornerstone of modern electronic information technology. In digital circuits, high and low levels are usually used to represent logic "1" and "0". Different logic gates can be used to implement different Boolean functions. AND gates and OR gates are the most The basic logic gates, the truth tables corresponding to AND gates and OR gates are as follows: [0003] input A input B Output F 0 0 0 0 1 0 1 0 0 1 1 1 [0004] Table 1: Truth table for logic AND gates [0005] input A input B Output F 0 0 0 0 1 1 1 0 1 1 1 1 [0006] Table 2: Truth Table for Logical OR Gates [0007] The logic gate made of the traditional CMOS structure has large...
