Preparation and Magnetic Properties of Mn-Zn Ferrite Nanoparticles and Magnetic Fluid
摘要
Abstract
Mn1-x Zn,Fe204 (x =0. 1, 0. 2, 0. 3) ferrite magnetic particles were prepared by chemical coprecipitation method. The structure and the average particle sizes were determined by X-ray diffraction (XRD) analysis, and it shows that the prepared particles are Mn-Zn ferrite nanoparticles. The saturation magnetization of samples was 25. 3 emu/g, 44. 4 emu/g and 30. 7 emu/g for x = 0. 1, 0. 2 and 0. 3, respectively, and which were measured by vibrating sample magnetometer( VSM ). Mn0.8 Zn0.2 Fe2O4 nanoparticles were used for ferrofluid preparation, which were suitably dispersed in aviation kerosene using oleic acid as the surfactant. Saturation magnetization and thermomagnetic properties of the ferrofluids were measured and discussed.关键词
