【摘要】 制备了配以不同表面活性剂和基液的几种接Zn的Fe3O4复合磁性液体．通过对其中磁性微粒颗粒度、分布均匀性的分析和复合磁性液体比饱和磁化强度、矫顽力等磁特性的测试，阐述了掺Zn量及表面活性剂等因素对世性液体磁特性的影响，并对其磁性机理进行了探讨．更多还原

【Abstract】 The Zn-substituted Fe₃O₄ composite magnetic fluids were obtained with different surfactants and solvens. Its specific saturation magnetizahon, the coercivity（Hc） and the size as well as the homogeneity of the composite magnetic particles were systematically measured. The influence of the Zn content and surfactant on their magnetic properties was explained.更多还原
