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.



Not quite. Best I can gather is the material is different (ferrous material implies iron, but I think this describes the behavior, not the constituent parts).
I think that’s right, but maybe I’m annoingly wrong enough to elicite a smarter person to correct me 🫣
