| Abstract: | In this work, we report three-dimensional Monte Carlo simulations of a polydisperse magnetic fluid sample based on magnetite nanoparticles surface coated with dodecanoic acid dispersed in hydrocarbon. Monodisperse simulations are also performed and indicate that polydispersity is a key issue. Our simulations are consistent with both static magnetic birefringence and magnetic resonance measurements for a particle volume fraction smaller than 4%. |
