摘要：

Iron particles with diameters of less than 100 nm were prepared using microemulsions and their sizes were related to the size of the microdroplets in the microemulsions. A certain control over the magnetic behavior of the resulting materials was achieved through a process of fine tuning of the size of the particles. This control allowed the modification of this behavior from superparamagnetism to ferromagnetism at a given temperature by acting on simple and easily modifiable parameters of the fabrication procedure.
