摘要：
Mn-Zn ferrite nanoparticles (Mn1-xZnxFe2O4) are synthesized by a hydrothermal precipitation approach using metal sulfate solution and aqueous ammonia. The analysis methods of XRPD, TEM, TGA, and VSM are used to characterize the magnetic nanoparticles. Through the characterization of the precipitated nanoparticles, the effects of the reacting component proportions and preparation techniques on the Curie temperature, the magnetization, and the size distribution of Mn-Zn ferrite nanoparticles are discussed. Furthermore, the Mn-Zn ferrite nanoparticles are used to prepare ferrofluid. Variation of the magnetic properties of the ferrite nanoparticles, with the composition content x of Zn and the magnetic moment of the nanoparticles are discussed. (c) 2006 Elsevier B.V.
