We have developed the main magnet with independent intellectual property rights, and the main magnetic structures are as follow: the magnet gap is less than 70 mm, the magnetic field strength is 1.2~1.5 T, the diameter of the spherical space is less than 60 mm, the uniformity is 1~0.5 ppm, and the weight is less than 1200 kg.
To this end, micron scale magnetic structures are fabricated using cleanroom technologies.
Spin-based Nanostructures: When magnetic structures are shrunk down to single-atom or single-molecule sizes, then quantum spin effects dominate their behavior.
In addition to the potential storage applications, the researchers noted that atomic-scale magnetic structures are also of scientific interest because they may be harnessed for quantum computing, a technology that would be far faster than current computers for some specialized uses.
Jumps in magnetic field in planar magnetic structures were tangential discontinuities across which there was no mass flux, with a few exception.
The experimental demonstration of the properties of field confinement of Abele's yokeless magnetic structures was first established in the 1990s, at the US Army Electronics Technology and Devices Laboratory, Fort Monmouth, NJ and later at the laboratory of Sumitomo Special Metals, Japan, where a large scale experimental model was built.
The magnetic structures are explained theoretically using a simplified model Hamiltonian, that involves competing nearest- and next-nearest-neighbor exchange interactions, single-ion anisotropy, pseudodipolar interactions, and Dzyaloshinskii-Moriya interactions.
The final magnetic structure is determined by the shape of the system or the locations of defects.
It suggests that a planar magnetic structure is made of layers of plasmas bounded by several tangential discontinuities, and in a few cases, there is an interaction between the layers.
