Why Nobody is Talking About Fast-Moving Magnetic Particles And What You Should Do Today

Rather than writing and reading information one bit at one time by altering the orientation of magnetized particles onto a surface, as today's magnetic disks perform, the newest machine could make use of tiny disturbances in magnetic orientation, which have been dubbed "skyrmions." These virtual particles, that occur to a thin metallic film sandwiched against a film of steel that was different, could be controlled and manipulated with components, also may store information for extended periods with no need for more electricity input.

"One of the largest missing bits" needed to make skyrmions a practical data-storage medium, Beach says, was a reliable way to create them when and where they were needed. "So this is a significant breakthrough," he explains, thanks to work by Buettner and Lemesh, the paper's lead authors. "What they discovered was a exact quick and effective way to publish" such formations. But an alternative way of reading the data may be possible, using an additional metal layer added to the other layers.

By creating a particular texture on this added layer, it may be possible to detect differences in the layer's electrical resistance depending on whether a skyrmion is present or not in the adjacent layer. "There's absolutely no wonder it would work," Buettner states, it's only a matter of figuring out the most needed engineering growth. The crew is currently pursuing this and also other strategies to tackle the read out question. The researchers plan to explore better ways of getting the information back out, which could be practical to manufacture at scale.

The key to being able to create skyrmions at will in particular locations, it turns out, lay in material defects. By introducing a particular kind of defect in the magnetic layer, the skyrmions become pinned to specific locations on the surface, the team found. Those surfaces with intentional defects can then be used as a controllable writing surface for data encoded in the skyrmions. The team realized that instead of being a problem, the defects in the material could actually be beneficial.

The X-ray spectrograph is "as a microscope with no lenses," Buettner explains, so the image is reconstructed mathematically from the collected data, rather than physically by bending light beams using lenses. Lenses for X-rays exist, but they are very complex, and cost $40,000 to $50,000 apiece, he says. New study has revealed that an exotic type of magnetic behavior discovered just afew years past holds good promise as a method of keeping info -- just one that could overcome fundamental limits that might likewise be indicating that the end of "Moore's Law," which explains the ongoing improvements in computation and data storage within recent decades.

The system also potentially could encode data at very high speeds, making it efficient not only as a substitute for magnetic media such as hard discs, but even for the much faster memory systems used in Random Access Memory (RAM) for computation.

The new findings are reported this week in the journal Nature Nanotechnology, in a paper by Beach, MIT postdoc Felix Buettner, and graduate student Ivan Lemesh, and 10 others at MIT and in Germany.

A staff led by MIT affiliate professor of materials science and engineering Geoffrey Beach recorded that the presence of skyrmions, although the particles' locations on a surface were entirely random.
