| Abstract: | A new and special experimental method is applied to the preparation of magnetic nan oparticles of Fe3O4. Using both physical and chemical means, the Fe3O4 nanoparticals with the same size and dispersal are prepared. The nanoparticals of Fe3O4 which have the average size of 5nm to 10nm are got through changing the react time and the distance between magnet and react region. The magnetic properties of the nanoparticles are measured by AGM. |
