Abstract

The magnetic properties of manganese (Mn) doped zinc oxide (ZnO) tetrapod structures were studied by diffusion doping at temperatures 600 and 800°C. The samples showed clear magnetic hysteresis at 5K and Curie temperature was determined to be ∼50 K. The sample diffused at 600 °C exhibited higher Mn concentration and higher remnant magnetization at 5 K. The samples exhibited very high coercive field, which is about one order of magnitude higher compared to values reported for ZnO:Mn thin films.
