【Abstract】 CoFe\-2O\-4ultrafine particles is produced with copripitate mthode.By controlling acid etch, stable magnetic liquid, in which there is not surface activator,is prepared.The particles are analyzed with X\|ray diffraction ,vibrating sample magnetometer, transmission electron microscopy and scanning tunnel microscopy. The mechanism of preparing magnetic liquid by coprecipitate\|acid etch is studied.更多还原
