Ten Key Tactics The Pros Use For Fast-Moving Magnetic Particles

The X-ray spectrograph is «as a microscope with out 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. 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. This boundary region can move back and forth within the magnetic material, Beach says.

Skyrmions are little swirls of magnetic orientation within these layers, Beach adds. Instead of writing and reading information one bit at one time by changing the orientation of magnetized particles on a face, since the current magnetic discs perform, the new machine would use small spikes in magnetic orientation, and which happen to be dubbed «skyrmions.» These particles, that occur to a film sandwiched against a film of metal, could be manipulated and manipulated using electric fields, also will store information for extended periods.

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. «One of the biggest 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 that is a significant breakthrough,» he explains, thanks to work by Buettner and Lemesh, the paper's lead authors.

«What they uncovered was a extremely fast and reliable means to produce» 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 question it works,» Buettner says, it is merely an issue of finding out the needed engineering progress.

The team is currently chasing this and potential strategies to tackle the question. 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.

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

Now, Beach has collaborated with others to demonstrate experimentally for the first time that they can create these particles at will in specific locations, which is the next key requirement for using them in a data storage system. New research has demonstrated that an exotic sort of magnetic behaviour discovered just several years ago holds excellent promise for a manner of keeping data — one that can over come basic restrictions which may likewise be signaling at the end of «Moore's Law,» that clarifies why the continuing developments in computation and information storage over recent years.
