Abstract :
Ternary mixtures of organic solvent, surfactant, and aqueous solution forming a single phase are used for the synthesis of magnetic particles of magnetite. These particles, washed and covered with oleic acid, were stabilized in a carrier liquid, producing a magnetic fluid. X-ray diffraction, transmission electron microscopy, and magnetic measurements of the particles, and the prepared liquid are reported
