摘要
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 Zn1-xMxO (M=Fe, Co, Ni) nanosystems is observed for various concentrations (x) of the doped ions. The anisotropies of Zn1-xMxO when synthesized by three different techniques viz, chemical precipitation, pulsed laser deposition and sol-gel, have been compared. The temporal reversal paths of Zn1-xMxO magnetic moments are elucidated and their switching times are reported.
