Figure 7From: Influence of structure of iron nanoparticles in aggregates on their magnetic properties Graph of limit distances of interacting aggregate with one nanoparticle. Solid line represents attractive magnetic force between an aggregate and a nanoparticle on which gravitation force effects. The dashed lines represent attractive magnetic force between a nanoparticle attracting an aggregate. Square marks represent data computed by averaging, triangle marks stand for sum of magnetic forces of a nanoparticle and all nanoparticles in an aggregate.Back to article page
