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 𝑇c ferromagnetism was observed. These Mn–ZnO whiskers may find their potential applications in spintronic field.
