| In recent time, magnetic nanoparticles have become widely used for preparation of advanced magnetic materials and also for biomedical applications. Requirement for preparation of particles of suitable shape and size has appeared, hence, various methods have been developed. Here we present rapid and energy saving one-pot solvothermal synthesis using microwave pressurized system. This method allows tuning the size of the particles as well as their magnetic properties. Spherical Fe3O4 nanoparticles are obtained in 30 min; They are uniform: with average dimensions of 200 nm and exhibit ferromagnetic behavior dependent on synthesis temperature. |
