A clearer look at critical materials, thanks to refrigerator magnets

Feb 02, 2026 Researchers adapted ARPES to work in magnetic fields using nanoscale alternating magnets that confine fields near a sample, letting photoelectrons travel straight. (Nanowerk News) With an advanced technology known as angle-resolved photoemission spectroscopy (ARPES), scientists are able to map out a material’s electron energy-momentum relationship, which encodes...
