Abstract

The invention discloses a reconfigurable logic gate based on magnetic Skyrmion, and belongs to the technical field of magnetic devices. The magnetic Skyrmion with the polarity of +1 or -1 is used forexpressing logic 1 and logic 0, and the data loss and misreading problems are improved. Through changing the connection port of the voltage-controlled magnetic anisotropy gate power source, the conversion between the AND gate and OR gate is achieved, and the manufacturing technology is greatly optimized.0Under the drive of current, the logic operation based on the magnetic Skyrmion is achieved byusing the characteristics that the twisted magnetic Skyrmion can move along the antiferromagnetic boundary, the two twisted magnetic Skyrmions can be integrated to form one twisted magnetic Skyrmion,the magnetic Skyrmion with the topological charge of +1 or -1 can be converted into the twisted magnetic Skyrmion, and the twisted magnetic Skyrmion can also be converted into the magnetic Skyrmion with the topological charge of +1 or -1. The logic gate provided by the invention has the characteristics of small size, low power consumption, high stability and high computation speed.

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 l...
