Title: Dilution series approach for investigation of microstructural properties and particle interactions in high – quality magnetic fluids
Published In: Eur. Phys. J. E, Vol. 7, pp. 209–220
Description: The aim of the paper is to study the deviation of magnetic properties of the magnetic fluids prepared for this study, from ideal (Langevin) behaviour, i.e. to estimate particle interaction influence and dimensions and influence of particle aggregates, as well as to explain the related effects observed. We also determine the particle coupling parameter, the particle nonmagnetic layer thickness, and the particle distribution, which are fundamental for sample characterization. A comparison of the studied magnetic fluids with each other, with respect to microstructure formation and particle interaction strength is finally done. For these purposes, a concentration dependence study, following the proposed "dilution series approach", is performed. Three series of dilutions of three types of magnetic fluids were prepared and analyzed.
