Altermagnetism Experimentally Demonstrated

The direction of an electron spin is determined by the direction of motion of electrons. (ill.: Hans-Joachim Elmers)

Researchers have been able to visualize the third class of magnetism, called altermagnetism, in action. Ferromagnetism and antiferromagnetism have long been known to scientists as two classes of magnetic order of materials. Back in 2019, researchers at Johannes Gutenberg University Mainz (JGU) postulated a third class of magnetism, called altermagnetism. This altermagnetism has been the subject of heated debate among experts ever since, with some expressing doubts about its existence...
