New Kind Of Magnet, Singlet-Based Magnet, Discovered By Scientists


Even though we don’t think about magnets too often, they have many uses in our day-to-day life. Also, they have significant purposes in science and technology, including in data storage applications, known as magnetic recordings which mean storing data on a magnetized medium as non-volatile memory. Now, the scientists discovered a new kind of magnet that might change the game.

“There’s a great deal of research these days into the use of magnets and magnetism to improve data storage technologies,” said Andrew Wray, an assistant professor of physics at New York University.

Scientists Discovered A New Kind of Magnet, Singlet-Based Magnet

A team of scientists from the New York University, headed by Andrew Wray, identified a new type of magnet, known as “singlet-based” magnet. This magnet boasts “fields that pop in and out of existence as opposed to the small magnetic constituents that exist in its current counterparts,” according to Interesting Engineering. In theory, a singlet-based magnet seems unstable but, in reality, it is more flexible than regular magnets.

“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. There’s also a big difference in how this kind of magnetism couples with electric currents. Electrons coming into the material interact very strongly with the unstable magnetic moments, rather than simply passing through. Therefore, it’s possible that these characteristics can help with performance bottlenecks and allow better control of magnetically stored information,” explained Andrew Wray.

“This material had been quite an enigma for the last couple of decades–the ways that magnetism and electricity talk to one another inside it were known to be bizarre and only begin to make sense with this new classification,” added Lin Miao, also from the New York University.
