MSD Researchers Solve a Spintronic Mystery

Wladek Walukiewicz and Kin Man Yu of the Materials Sciences Division, in collaboration with Notre Dame researchers, appear to have resolved a long-standing controversy regarding gallium manganese arsenide, one of the most promising semiconductors for spintronic technology. They’ve determined the source of the ferromagnetic properties that make gallium manganese arsenide such a hot commodity for the smaller, faster and much cheaper data storage and processing of spintronic devices. Collaborators included Margaret Dobrowolska, Kritsanu Tivakornsasithorn, Xinyu Liu, Jacek Furdyna and Mona Berciu. More>


  1. These are interesting new results on magnetism in doped GaAs, which are well written up.
    Kudos to all.
