Abstract

In this work, we carry out structural analysis of ferromagnetic Mn-doped ZnO thin films deposited by radio frequency magnetron sputtering, using transmission electron microscopy (TEM) and high resolution x-ray diffraction. On top of sapphire (0001) substrates, Mn rich precipitates and an interface reaction layer are observed following the deposition of Zn(Mn)O layers above 500°C. The crystalline quality of ZnO layers deposited by magnetron sputtering is highly improved at 500°C as well as the measured ferromagnetic response.
