Wan, G. Tang, Y. Qian] Single-crystal Fe3O4 nanoparticles with uniform size and relatively better monodispersity have been successfully synthesized via a facile room temperature coprecipitation route in the present of poly(vinyl pyrrolidone) (PVP). This method does not require high temperature, expensive and toxic starting materials, complicated procedure and toxic organic solvents. The magnetic properties of as-prepared samples were recorded on a superconducting quantum interference device magnetometer. Its blocking temperature is 140K. The hysteresis loops of single-crystal Fe3O4 nanoparticles at 300K and 10K show the transition from superparamagnetic to ferromagnetic behavior. And the maintenance of high saturation magnetization ascribes to the single-crystalline nature of these Fe3O4 nanoparticles. Springer-Verlag, 2006 Wan J.
