Room temperature ferromagnetism in Mn-doped zinc oxide nanorods prepared by hybrid wet chemical route

► Mn-doped aligned zinc oxide (Mn:ZnO) nanorod-films were synthesized by hybrid wet chemical route. ► Increase in atomic concentration of Mn (2.6-4.8 at%) did not affect vertical alignment. ► No observable secondary phases were present in the films. ► M-H hysteresis curves indicated that saturation magnetization (MS) increased with Mn concentration. ► Substitution of Mn2+ in the Zn2+ site was responsible for the observed room temperature ferromagnetism.
