Physicists observe a new form of magnetism for the first time

Boston MA (SPX) Jun 11, 2025
MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry "spintronic" memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are
