摘要：
Application of ZnO as a dilute magnetic semiconductor awaits consensus on the source of reported ferromagnetic behaviour in doped ZnO, whether due to dopant-defect interactions or formation of nanoclusters of the magnetic ion dopants. In a contribution to this search, we report on conversion electron Mössbauer Spectroscopy (CEMS) and magnetization studies on single crystal ZnO substrates implanted with Mn ions with energies and fluences designed to give flat implantation profiles with 3 and 7 at% concentration (samples ZnO:Mn1 and ZnO:Mn2). For CEMS measurements, the substrates were also co-implanted with 3.9 × 1015 cm-2, 60 keV 57Fe ions.
