Light-driven artificial ferrimagnet for memory

Caption

New artificial ferrimagnetic materials made of antiferromagnetically coupled Co/Gd/CoFeB trilayers enable reliable switching of magnetic states using a single femtosecond laser pulse. Developed with synchrotron analysis at NanoTerasu, these materials are compatible with magnetic tunnel junctions and could serve as key components in future high-speed, low-power memory and computing devices.
