Summary, etc. Magnetization reversal of magnetic moments in transition metal ions doped ZnO nanosystems has been studied in the present paper. Stoner-Wohlfarth model is used to illustrate the energy surfaces, magnetic hysteresis and the coherent switching behaviour of magnetic moments. Low magnetic anisotropy in Zn<sub>1</sub><sub>-x</sub>M<sub>x</sub>O (M=Fe, Co, Ni) nanosystems is observed for various concentrations (x) of the doped ions. The anisotropies of Zn<sub>1</sub><sub>-x</sub>M<sub>x</sub>O when synthesized by three different techniques viz. chemical precipitation, pulsed laser deposition and sol-gel, have been compared. The temporal reversal paths of Zn<sub>1</sub><sub>-x</sub>M<sub>x</sub>O magnetic moments are elucidated and their switching times are reported.
