摘要：
Colloidal iron oxide magnetic nanoparticles were synthesized from high temperature reaction of Fe(acac)(3) solution. The size of particles was easily tunable from 4 to 22 nm in only one step in the synthesis process. From TEM images the particles showed cubic-faceted shape with good homogeneity and narrow size distribution. Preliminary magnetic measurements show the usual superparamagnetic and blocked regimes depending on temperature.
