A team of scientists at New York University has developed a new type of magnet -singlet-based magnet- that holds promise for enhancing the performance of data storage technologies.
The magnet consists of USb2 (a compound of uranium and antimony) and thus it generates magnetism in a different way than any other magnet known to scientists. By contrast, the newly uncovered singlet-based magnet has fields that pop in and out of existence, resulting in an unstable force—but also one that potentially has more flexibility than conventional counterparts.
Andrew Wray, an assistant professor of physics at New York University, who led the research team said, “There’s a great deal of research these days into the use of magnets and magnetism to improve data storage technologies. Singlet-based magnets should have a more sudden transition between magnetic and non-magnetic phases. You don’t need to do as much to get the material to flip between non-magnetic and strongly magnetic states, which could be beneficial for power consumption and switching speed inside a computer.”
This is rather strange. The fact that the magnetic field is unstable sounds like a hindrance to anyone hoping to apply it in the real world - but, they already reckon they can use this in data storage. Good luck to them on getting this to work - and, indeed, in finding other applications!
