Box 11100, Aalto University, FI-00076, Finland Using magnetization measurements, we show that point defects in graphene – fluorine adatoms and irradiation defects (vacancies) – carry magnetic moments with spin 1/2. Both types of defects lead to notable paramagnetism but no magnetic ordering could be detected… CONTINUE READING
