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.
Yeah. I was confused for moment. Wait they found third field in addition to the electric and magnetic fields? Like that would be “throw Einstein out the window” level change.
Specifically they called it a “phase” here, so not another field, more akin to like a new way a magnet can behave (i think)
