Microwave anneal effect on magnetic properties of Ni0.6Zn0.4Fe2O4 nano-particles prepared by conventional hydrothermal method

► Hydrothermal method synthesis of ferrite nano-particles at low temperature. ► Microwave annealing has slight effect on size of ferrite nano-particles. ► Microwave annealing enhances the densification of ferrite nano-particles. ► Microwave annealing greatly increases saturation magnetization of the particles. ► Rapid synthesis of high performance ferrite nano-particles by microwave annealing.
