摘要: The formation of agglomerates by salt-induced double layer compression magnetic nanoparticles in the absence and presence an external field was investigated experimentally as well computationally this study. structures were analyzed through scanning electron microscopy proved to be highly porous composed large spaces among branches a convoluted network. In field, such network observed oriented no particular direction. contrast, when agglomeration process allowed occur these appeared predominantly one A modified Discrete Element Method applied simulate both field. simulations show that occurred random clusters which then joined form anisotropic forces, rotated align along direction final formed consisted largely elongated nanoparticles.
