Researchers propose a non-invasive quantum sensing method using diamond defects to identify altermagnets, a novel magnetic state that could enable faster, energy-efficient electronics. This technique addresses the critical need to measure intrinsic material properties without experimental perturbation, potentially unlocking the potential of over 200 candidate materials. Validating this approach is a key step toward realizing next-generation information transport technologies based on this third category of magnetism.

A New Magnetism Detected With Quantum Sensing

University at Buffalo physicists propose a quantum sensing system to identify altermagnets, a recently discovered type of magnetism, using magnetic.

University at Buffalo physicists are proposing a quantum sensing system that could simplify the identification of altermagnets, a recently discovered third category of magnetism potentially combining the strengths of both ferromagnets and antiferromagnets. For nearly a century, these two types of magnets defined the field; however, Libor Šmejkal and Jairo Sinova of Johannes Gutenberg University of Mainz first proposed altermagnets after encountering an effect they couldn’t explain. Altermagnets may offer a path…
