UC San Diego Engineers Optically Switch Magnets
6 min read
Scientists at UC San Diego demonstrated optical switching in a nine-layer magnetic structure, achieving speeds more than 1,000 times faster than conventional methods. Published in Nature Communications on October 27, 2026, the study overcomes previous thickness limits by reshaping laser beams to concentrate energy, potentially enabling compact, high-density memory devices for future electronics.
