Abstract: 
  • In this report the correlation between ferromagnetism and the oxygen vacancy in thin film ZnO doped with Mn and Co is investigated. This was done by annealing samples in both air and nitrogen and performing photoluminescence and VSM measurments. A weak ferromagnetic signal was observed in ZnO:Mn, the saturation value of which could be increased when annealed in nitrogen and decreased when annealed in air. The ZnO:Co samples however showed no ferromagnetic signals. The results from the Mn samples indicate that the oxygen vacancy does indeed play a part in the observed ferromagnetic response.
