Quantum Sensors Detect Third Type of Magnetism
TL;DR. Physicists developed a method using quantum sensors to identify altermagnets, a third type of magnetism that blends properties of ferromagnets and antiferromagnets. - Altermagnets could reshape information transport due to their rapid switching and controllable electronic properties. - The detection method relies on observing how tiny magnetic defects in diamond react to altermagnetic spins. - Researchers aim to verify altermagnetic behavior in over 200 materials through this new experimental approach.
- Altermagnets combine features of ferromagnets and antiferromagnets, offering potential for energy-efficient information storage.
- A new theoretical technique tracks altermagnet presence by observing magnetic defects in diamond using quantum noise spectroscopy.
- The method could help identify practical altermagnetic materials from over 200 suspected candidates for future tech applications.
