Altermagnets are a newly recognized class of materials that show momentum-dependent spin splitting without requiring spin-orbit coupling (SOC) or net magnetization. These materials have recently garnered international attention.
A research team led by Prof. Junwei Liu from the Department of Physics at the Hong Kong University of Science and Technology (HKUST), together with experimental collaborators, published groundbreaking findings in Nature Physics. Their work reports the first experimental observation of a two-dimensional layered altermagnet that remains stable at room temperature, confirming theoretical predictions made by Prof. Liu in Nature Communications in 2021.
