Chiba University Researchers Unmask Hidden Magnetism of Altermagnets with New Light-Based Technique
Researchers at Chiba University in Japan have developed a new light-based technique to detect altermagnets, a hidden class of magnetic materials. By probing crystals with circularly polarized light, they can reveal the self-canceling spin structure, enabling the discovery of materials for faster, more energy-efficient spintronic devices.
