Researchers have achieved the first real-space imaging of altermagnetic domains in RuO₂ using a novel thermal imaging technique. By combining lock-in thermography with the spin-dependent Peltier effect, the team visualized micrometer-scale magnetic domains and demonstrated controlled domain manipulation through magnetic field cooling. This breakthrough provides robust experimental evidence for altermagnetism in RuO₂ and establishes a new approach for characterizing this emerging class of magnetic materials, with significant implications for future spintronic devices.

A new approach to accurately imaging objects with complex shapes and varying degrees of "shininess" could enable high-precision applications in virtual and mixed reality settings, industrial inspection and medical imaging.

New study demonstrates that the direction of a magnetic field can influence how slightly different versions of the same biological molecule behave, revealing a previously unrecognized link between magnetism, electron spin, and isotope chemistry. By showing that these effects depend on both molecular structure and magnetic orientation, the research introduces a new factor that could help explain how chemical processes operate in biological systems and may offer new approaches for isotope separation and analysis.
