Scientists who discovered a third form of magnetism win major physics prize

6 hours ago by Rimu to c/science

Physicists have uncovered a hidden third form of magnetism that challenges more than 100 years of established physics. Called altermagnetism, the discovery could transform future computing and electronics while opening an entirely new frontier in quantum research.

I didn't even know there was a second form of magnetism

Here's the bit that sort of explains things:

"For more than 100 years, physicists generally divided collinear magnets into two fundamental categories: ferromagnets and antiferromagnets.

Ferromagnets have an overall magnetic alignment that produces a net magnetization. These materials are essential to many magnetic memory technologies used today. In conventional antiferromagnets, opposing magnetic moments cancel one another, leaving no overall magnetization and producing electronic behavior very different from that of ferromagnets.

Altermagnetism introduces a surprising third possibility.

Like antiferromagnets, altermagnets have magnetic moments that cancel out, resulting in no net magnetization. However, their electrons can exhibit properties previously associated with ferromagnets.

This unusual combination allows altermagnets to support electrical currents with strongly polarized electron spins while also displaying extremely rapid magnetic dynamics. Those characteristics could make them valuable for a new generation of spintronic devices, potentially advancing the speed and capabilities of future information technologies."

So not a third form of magnetism but a third form of magnets.

Basically a semiconductor for magnetism.
