Diamond quantum sensor could reveal elusive altermagnets
Key Points
The article discusses the discovery of altermagnets, a third category of magnets that could potentially combine the best qualities of ferromagnets and antiferromagnets. Altermagnets are being studied for their technological potential, particularly in creating faster and more energy-efficient electronics. The article highlights the significance of this discovery and its potential impact on the field of electronics.
For nearly a century, there were two known kinds of magnets. Ferromagnets are the classic magnets that attract metal and keep pictures stuck to the refrigerator. Antiferromagnets hide their magnetism at the atomic scale but are increasingly prized for their technological potential. A third category discovered within the last decade may combine the best qualities of both. Dubbed altermagnets, they could someday help create faster, more energy-efficient electronics.
