PHYSICISTS CREATED A MAGNET THAT IS ONE ATOM THICK, THAT COULD HAVE APPLICATION IN QUANTUM COMPUTING

You may have heard of graphene, the ultra-thin wonder material that is a single layer of pure carbon, derived from graphene. Well, scientists at the University of Washington and the Massachusetts Institute of Technology (MIT) have just employed the same technique that is used for skimming graphene from graphite to develop the thinnest magnet ever created.

It is so thin, in fact, that it counts as the world’s first 2D magnet, with a thickness of just one atom. This counts as being functionally two-dimensional because electrons can only travel within the atomic sheet, akin to pieces moving on a chessboard. Up until now, no 3D magnetic substance has been able to retain its magnetic properties after being thinned down to a single atomic sheet.

The development demonstrates that magnetism can work in the 2D world, which could have major implications for building future quantum computers.

“In general, magnets have critical application in sensing and information technologies, such as modern hard-disk storage,” Xiaodong Xu, a University of Washington professor of Physics and of Materials Science and Engineering, told Digital Trends. “2D magnets may offer new opportunities in nanoscale spintronic devices along the same line of applications. However, since this is the first discovery of isolated monolayer magnet at the truly 2D limit, lots fundamental questions need to be addressed before figuring out the killer applications.”

Genuinely very cool. Also while I know this is an important advance, my mind just went to this song because I have the maturity of a 13 year old:
