【摘要】 制备了含强磁性Ｆｅ３Ｏ４的纯磁性液体胶体和掺入聚苯乙烯小球的磁性液体复合胶体样品，系统测量了样品的双折射效应和线二向色性，并对测量结果进行比较分析，认为磁性液体复合体中非磁性小球的不同排列影响了它的磁光特性更多还原

【Abstract】 Both pure Fe 3O 4 magnetic fluids and that containing polystyrene spheres composite magnetic fluids were prepared. The magneto optical effects of different samples were measured by the magneto optically modulated double frequency method. The author analyzed the results and suggested that the different arrangement of nonmagnetic spheres in the composite magnetic fluids affects its magneto optical property.更多还原
