Physicists have proposed a new method using quantum sensors to detect altermagnets, a recently discovered third type of magnetism. This technique tracks how altermagnets affect magnetic defects in diamonds, potentially transforming information transport. Researchers aim to test over 200 materials suspected to exhibit altermagnetic properties.
- 01Altermagnets combine properties of ferromagnets and antiferromagnets, potentially revolutionizing information transport.
- 02The detection method involves quantum noise spectroscopy and utilizes tiny magnetic defects in diamonds.
- 03Altermagnets exhibit unique spin patterns that influence how quickly diamond defects relax after rotation.
- 04The new approach is less invasive and more efficient than traditional methods requiring large particle accelerators.
- 05Researchers need to conduct empirical tests to validate the effectiveness of this detection technique.

In 2022, the discovery of altermagnets introduced a third type of magnetism, blending characteristics of ferromagnets and antiferromagnets. A recent study published in *Physical Review Letters* proposes a novel detection method using quantum sensors to identify these elusive materials. The technique tracks how altermagnets influence tiny magnetic defects in diamonds, specifically how these defects relax after being rotated. This method is expected to be less invasive and more efficient than existing techniques that often require large particle accelerators. Jamir Marino, a physicist at the State University of New York at Buffalo and co-author of the study, highlighted that altermagnets could significantly enhance information transport due to their unique spin patterns and rapid switching capabilities. The team plans to test over 200 materials suspected to be altermagnets to see if they behave as theorized, marking a potential breakthrough in material science and technology.
