Abstract

Vertically aligned Mn-ZnO whiskers were grown on sapphire substrate by a thermal chemical vapour deposition method. X-ray diffraction measurements indicate that samples are high-quality single crystals and c-axis oriented. Raman and XPS analyses revealed that Mn was incorporated into the ZnO lattice. Room temperature T c ferromagnetism was observed. These Mn-ZnO whiskers may find their potential applications in spintronic field.
