Magnetic Nano-magnetite is superparamagnetic, and has small size and quantum tunneling effect. The preparation methods for magnetite nanoparticles, such as co-precipitation, thermal decomposi- tion, hydrothermal and solvothermal, microemulsion, air oxidation, electrostatic spinning and microwave irradation, are revieucd. The latest development of the preparation method of magnetic magnetite nanopar- ticles are also introduced.
