Embodiment Construction

[0038] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0039] A method for constructing a two-dimensional magnetic vortex network of the present invention, the main body used is a channel structure processed by nanostructure micromachining on a thin film made of a ferromagnetic material containing Fe, Co or Ni elements ; The channel structure includes a ferromagnetic nanobelt 1, a ferromagnetic nanodisk 2, a bias nanomagnet 3 and a vortex coupler 4, such as figure 1 shown.

[0040] The first step: the construction method of one-dimensional three-magnetic vortex structure, such as Figure 2-4 shown. The main body is demagnetized along the -x direction, and a magnetic vortex structure is spontaneously generated in the ferromagnetic nanodisk 2 . figure 2 It is a magnetic force microscope image of the subject when a magnetic field is applied for the first time,...

Abstract

The invention belongs to the field of magnetic information storage and transmission, and relates to a construction method of a two-dimensional magnetic vortex network. An adopted main body is of a channel structure machined on a thin film prepared from a ferromagnetic material containing Fe, Co or Ni elements in a nanostructure micromachining mode. The channel structure comprises ferromagnetic nanobelts, ferromagnetic nanodisks, bias nano magnets and a vortex coupler. The number of the magnetic vortexes in the two-dimensional grid can be controlled by adjusting the number of the ferromagneticnanobelts, the number of the ferromagnetic nanodisks and the configuration of an external magnetic field. The technology can serve important fields of magnetic information storage, magnetic devices, magnetic topology structures, magnetic information processing and the like.

Description

technical field [0001] The invention belongs to the field of magnetic information storage and transmission, and relates to a method for constructing a two-dimensional magnetic vortex network. Background technique [0002] Magnetic vortex is a basic magnetic topological structure, which usually exists in ferromagnetic materials containing Fe, Co, Ni elements. In recent years, the research on important scientific issues such as the construction of magnetic vortex structures has attracted widespread attention in the academic community. The research on this issue will help realize the ultra-miniature, multi-functional, and low-energy consumption of spintronics-related magnetic devices. and high integration. However, the existing technical methods mainly focus on the construction of a single or two magnetic vortices, and there is no report on the construction method of a two-dimensional magnetic vortex network. Contents of the invention [0003] In order to solve the above pr...
