摘要： The paper demonstrates a possibility to use Small Angle Light Scattering (SALS) method realized in a conventional laboratory to investigate structuring processes in a magnetic fluid simultaneously exposed to a shear flow and external magnetic field. We have used custom made SALS-setup with a laser source combined with a microfluidic chip, an electromagnet and a magnetic circuit to obtain scattering images of a low concentrated biocompatible magnetic fluid with clustered iron oxide nanoparticles. Application of an external magnetic field drastically influences a physical behaviour of the fluid and this effect is directly related to aggregation of particles resulting in chains with a dimension of several micrometers. These chains results in the anisotropy of the scattering patterns. We have observed an influence of the field and flow on the intensity gradient of the obtained scattering patterns. Presented methodic opens broad perspectives to obtain microstructural information as well to evaluate structuring kinetics of the diluted magnetic suspensions using conventional laboratory conditions. Performed by us SALS measurements are accomplished with a full characterization of the fluid using magneto-rheometry, vibrating sample magnetometry, microscopy as well as dynamic light scattering.
