Who Else Wants To Learn About Fast-Moving Magnetic Particles?

As opposed to reading and writing data one piece at one time by simply changing the orientation of magnetized particles on a surface, since the current magnetic disks do, the newest system would use tiny interference in magnetic orientation, and which have been dubbed "skyrmions." These virtual particles, that occur to a picture sandwiched against a picture of metal, may be manipulated and controlled with fields, also may save data for extended periods without the need for energy input.

"One of the most significant 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 an important break through," he explains, thanks to work by Buettner and Lemesh, the paper's lead authors. "What they identified was a exact fast and productive way to compose" 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 no wonder that it would work," Buettner states, it really is only an issue of finding out the needed engineering improvement. The group will be currently pursuing this and also strategies that are possible to tackle the 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 "like a microscope devoid of lenses, so" 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 shown that an exotic type of magnetic behavior detected just many years ago holds excellent promise as a method of storing information -- one which could overcome basic restrictions which may otherwise be indicating that the end of "Moore's Law," which explains the continuing improvements in computation and information storage over 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.
