A New Dimension of Magnetism Explored
The direction of an electron spin is determined by the direction of motion of electrons. Credit: © Hans-Joachim Elmers / JGUResearchers at Mainz University 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…
