Influence of annealing on the structural and magnetic properties of epitaxial Zn1–xMnxO films grown by MOCVD on sapphire
Résumé
Thermal annealing of MOCVD grown Zn1–xMnxO layers between 300 °C and 1000 °C in an oxygen atmosphere modifies both their latttice parameters and their magnetic properties. Combined X-ray diffraction and EPR studies indicate a redistribution of intrinsic defects but persistent antiferromagnetic phase in the annealed films. (© 2006 WILEY-VCH Verlag GmbH & Co.
