Unusual ferromagnetism in CoSi nanowires from internal and interfacial defects

The diamagnetic semimetal CoSi presents unanticipated ferromagnetism as CoSi/SiO sub(2) nanowires (NWs). Using first-principles calculations, we offer physical insights into the origins of this unusual magnetism. Due to the distorted and dangling bonds near the NW surface with different bond lengths...
