Researchers have obtained the first conclusive evidence of an elusive third class of magnetism, called altermagnetism. Their findings, published Dec. 11 in the journal Nature, could revolutionize the design of new high-speed magnetic memory devices and provide the missing puzzle piece in the development of better superconducting materials.
the headlines about this are absolute dogshit and just fucking not true, they didn’t discover a “third form of magnetism”, they discovered a third kind of magnetic material.
I haven’t read about it in detail, but from what i can gather it’s like how things can be polarized in different ways, so imagine we only knew of linearly polarized light and just discovered circular polarization, basically.
it’s still just electromagnetism, but With Context
Ah, that was much easier to understand.
Thank you!
