Effect of oxygen annealing on the Mn2+ properties in ZnMnO Films
Résumé
We studied the influence of thermal annealing in oxygen on the physical properties of MOCVD grown Zn1-xMnxO thin layers. Annealing in the 300-1000 degrees C temperature range modifies both lattice parameters and magnetic properties of the layers. Correlation of the results from X-ray diffraction, EPR studies and Raman spectroscopy indicate a modi. cation of the Mn+2-related features in the ZnO matrix. (c) 2007 Elsevier B.V.
